Dynamic content not displaying my action

I came across this today and wanted to share. I couldnt figure out why my output from the teams adaptive card was not an option to select in my Compose (no body or anything available). 😭 Scenario: You have an action in your flow, for example a teams adaptive card, and want to use the output somewhere. Whether thats in a compose, set variable, update row, doesnt matter. What you try and do, it wont show.
