Sharing PowerApps makes things quick and easy to get apps in the hands of the right users. Since PowerApps integrates with so many services, both in and out of the Office365 ecosystem, it would be helpful to have a Power Automate trigger for when an app is shared.
Attributes related to the newly shared user could then be used to setup or permission them in connected services. For me, it would be awesome to instantly permission the user to the connected SharePoint list. This Flow would run under my account vs the app users account, and would avoid having to use an approval process to shift the work to an admin account.
I am the Admin and I gave them permission to use the app, I dont want to have to go to another site and give permission or have an approval to complete either.
