Currently there are four Microsoft Teams "Post a message" actions to choose from. That's very confusing. Why not just have one "Post a message" action that supports all scenarios through (advanced) configuration?
In addition I noticed messages posted by all "Post a message" actions will refer to the Flow author (or the user that caused the Flow to trigger). So even when a Flow was triggered by a Recurrence action, the resulting message will mention the Flow author. Also when you explicitly set the message to "Post as" a different account (i.e. Flow bot), the message will somehow refer to the Flow author. Why?
