Hi guys,
I'm building a flow which has the following structure:
It, will be triggered When Keyword it is mentioned in a chat
This Keyword will to popup an Adaptive Card in a IM within the the user that had used the keyword.

My issue is, I can't set it dynamically to get the user id which has used the trigger to add into the Adaptive Card recipient
I've already tried to use:
<at>username@domain.com</at>
triggerbody()?['from']?['user']?['id']
but no luck
