Question Backing up a system app?

[groston]

On my Pixel 7Pro, I use the default phone app, specifically com.google.android.dialer version 174.0.764060808. Is there some method, OTHER THAN the default google cloud-based backup, to backup the app (so that I can copy the data to a new phone)? I thought about using adb, but that which I have read suggests that adb backup might not work with Android 16.
