Thank you for your explaination! I noticed that this pr(MM-54416: Channel Bookmarks Web UI by calebroseland · Pull Request #25889 · mattermost/mattermost · GitHub) about channel bookmark UI has been merged into master branch and was part of milestone 9.11. In this PR, webapp operations videos are listed, that’s awesome. So how to do that in 10.1.1? Or this feature is temporarily disabled in frontend? If the answer is the later one, when will this feature be enabled completely?
