Hi All,
Quite new to the whole Power Platform, having come from a traditional software development background, and completely blown away with how good, and how supportive these forums are. Apologies if this isn't the most suitable forum however.
I have a scheduled flow that routinely queries a SharePoint list and sends out announcements and reminders to a designated Teams Channel. I want to be able to prevent none moderators from replying to these messages, as you can do when manually creating posts:

I can't see any way to do this using the [Post message in a chat or channel] action.
Any help or support would be gratefully received.
Mike
