The computer-implemented method of claim 1, wherein the message digest comprises a plurality of messages, including the first message and the second message, and wherein the plurality of messages can be filtered based at least in part on a characteristic.8. The computer-implemented method of claim 1, wherein the first priority and the second priority are determined using a machine-trained model or a set of rules.9. The computer-implemented method of claim 1, wherein the first priority is determined based at least in part on an originating source, a type of message, a topic associated with the first message, or content of the first message.10. A system comprising:one or more processors; andone or more non-transitory computer-readable media comprising instructions that, when executed by the one or more processors, cause the system to perform operations comprising:receiving messages from at least a user account and an application, wherein the messages are associated with a virtual space that is one of a plurality of virtual spaces accessible via a first section of a user interface associated with a group-based communication platform;determining, based on a first criterion being satisfied, a first priority associated with a first message of the messages, wherein the first priority is associated with first metadata of the first message;determining, based on a second criterion being satisfied, a second priority associated with a second message of the messages, wherein the second priority is associated with second metadata of the second message;causing, based at least in part on the first metadata and the second metadata, the first message and the second message to be aggregated in a message digest, wherein the message digest is presented as a single message within an integrated data feed of the messages presented via a second section of the user interface and wherein the message digest is associated with an actuation mechanism; andin response to receiving an indication of an interaction with the actuation mechanism, causing the first message and the second message to be presented individually via a third section of the user interface.11. The system of claim 10, wherein:the first message is presented via the third section of the user interface in association with a first presentation characteristic based on the first priority; andthe second message is presented via the third section of the user interface in association with a second presentation characteristic.12. The system of claim 11, the operations further comprising:receiving a third message associated with the virtual space, wherein the third message is associated with third metadata; andbased at least in part on a determination, based on the third metadata, that the third message is associated with a third priority, causing the third message to be presented via the second section of the user interface, wherein the third message is presented in association with a third presentation characteristic, corresponding to the third priority, that is different than at least one of the first presentation characteristic or the second presentation characteristic.13. The system of claim 10, the operations further comprising, based at least in part on the first metadata and the second metadata indicating that the first message and the second message are associated with a same priority, generating the message digest for presentation via the user interface.14. The system of claim 13, wherein:the first metadata is further associated with at least one of a first originating source, a first date, or a first time; andthe second metadata is further associated with at least one of a second originating source, a second date, or a second time,wherein generating the message digest is further based at least in part on a determination that at least one of (i) the first originating source and the second originating source are a same originating source, (ii) the first date and the second date are a same date, or (iii) that the first time and the second time are within a period of time.15. The system of claim 10, the operations wherein the first priority and the second priority are determined using a machine-trained model or a set of rules.16.
