Update PowerApps Email Address

I have an existing Microsoft PowerApps application that the previous developer wired to an old company email account. I simply need that email reference updated so the app now works with my current company address. I’m not asking for any additional features or design tweaks—just replace the old email wherever it is used, confirm the app still functions exactly as before, and hand it back. Please locate every spot in the app (or its connected Power Automate flow, if one is involved) where the old address appears, swap in the new one I’ll provide, test that all existing actions still run, and then share the refreshed .msapp file or a direct cloud update along with brief notes showing where the change was made. Once it opens, sends, and saves data exactly like before—only under the new email—the job is done.
