There is an existing post_a_message MS Teams Spoke Action that allows you to post a message to a MS Teams Channel. The issue is that you cannot tag a person to the message. This feature is super handy. We use it the tag the next on-call person in the rotation. I would add a new SM Teams Spoke Action that allows to you post in a channel and tag a person in that channel.
