When you send an approval workflow into Teams using Adaptive Cards, for every new step when the process needs inputs from the user, there is a new card created and sent.
Do you know that right now there is a new trigger in Power Automate which allows to get inputs from the users and refresh the existing card generated in Microsoft Teams?
Tomasz “The new action Update an adaptive card in a chat or channel has arrived. With it you are now able to update (or replace) an Adaptive Card sent to Microsoft Teams using Power Automate. Super cool!”
