Within Power Automate we are making use of the "Post message in a chat or channel" and "Post adaptive card in a chat or channel" actions. When using either of those, the notification text within both Windows and iOS only shows you a a generic 'new message/card has been posted', eg
(<user> has posted a new message)
How can you modify this default notification text? When using the good old incoming webhook connector, you can resolve it by adding summary before the adaptive card attachment, webhooks - Push Notifications/Toasts Summary for Adaptive Cards on Microsoft Teams - Stack Overflow, eg
I've already tried to modify the subject, append a { summary: "This is a new notification"} json body, include summary in the adaptive card attachment, none of those work.
