I have a Teams App that was uploaded which was working. Now we want to push an update to it. But we dont have the original manifest file or package in order to edit in App Studio. Is there a way to download what was used to create the App from what is now uploaded?
An idea - but it may not fit your situation - is if it were a power app and the user was still in the organisation, they can download the msapp package via https://make.powerapps.com or if they share the app with you
