In at least one example, the first section 202 of the user interface 200 can include a second subsection 208 that includes user interface elements representing communication channels. In some examples, the communication channels can include public channels, private channels, shared channels (e.g., between organizations), single workspace channels, cross-workspace channels, combinations of the foregoing, or the like. In some examples, the communication channels represented can be associated with a single workspace. In some examples, the communication channels represented can be associated with different workspaces (e.g., cross-workspace). In some examples, the communication channels represented can be associated with combinations of communication channels associated with a single workspace and communication channels associated with different workspaces.
