Get output from Adaptive Card choice sets
Adaptive cards is the name for the pop-up you can get in Teams, with custom content asking you to confirm something, or to submit a remark. One way of creating them is through Adaptive card Designer (JSON).
Another way is to use the new Cards (preview) method in PowerApps maker - find out how here: Microsoft Learn Page - https://learn.microsoft.com/en-us/power-apps/cards/overview/?wt.mc_id=DX-MVP-5005318
If you want to use your adaptive card as for example an approval, or you want the color choice you need to get the data that the card receives.
