In some examples, the user interface 200 can be associated with one or more user interface elements 224 that indicate (existing) subscriptions associated with the user (e.g., User F) and/or the communication channel (e.g., Channel D) (or direct message, board, etc.). The user interface element(s) 224 can correspond to the user interface element(s) 156 described above with reference to FIG. 1. In some examples, such user interface element(s) 224 can include an indication of a third-party platform (e.g., an application associated therewith) associated with the subscription and a name or title of an object with which the subscription is associated. In some examples, such user interface element(s) 224 can be associated with actuation mechanism(s) that when actuated can enable one or more operations. Additional details are provided below.
