Hi Sir, I'm facing a challenge with using Adaptive Cards in custom topics within Copilot Studio. I'm designing an Adaptive Card where users need to enter organizational email addresses. I want to implement a feature that provides email suggestions as users start typing. However, I’ve been stuck on this for the past two weeks. Could you please assist me with this?
