It sounds like you are asking for Private Channels which should release later this calendar year. You can follow the topic at: https://microsoftteams.uservoice.com/forums/555103/suggestions/16911079
A workaround, for the time being, would be to create a team “support services team” and have “data management” and “tech support” be their own channels.
Thank you for your feedback!
The ability to delete Bot messages feature has been added to the backlog. Thank you for your feedback!Anonymous shared this idea ·
This continues to be on our backlog due to prioritization of other work items. We will update when there is more to share.
