Include a link in the app to the host webpage to check for app updates

Could there be an option in SAB to enter the URL from which the app can be downloaded so that users could easily open the page to check for updated versions of the app?

Maybe not needed as this can be added on the About page!

This is useful for situations where the Apps are not published to Google Play Store. (For SAB, RAB, DAB).
I’ve seen users put this information on the About page of the app.
