[FEATURE REQUEST] "Hide Until Next Message" on Big Team Channels

The feature to "Hide Until Next Message" is visible when clicking the gear on Small Teams as well as 1-on-1 Chats, however, this option is missing from Big Teams or the channels listed under a Big Team. I would appreciate such a feature to facilitate the sane management and display of a lot of teams or teams with a lot of channels.

The issue names no files, tests, or entry point. Start by locating the existing “Hide Until Next Message” control for Small Teams and 1-on-1 Chats, then trace how visibility is handled for Big Teams and their channels; done means the option works consistently there as well.
