I've recently setup wired Android Auto and its been working great, it redirects all music and sound playback except for phone calls using the GrapheneOS default phone app.
The only available options during a call is the phone itself or the phone speaker, i've enabled the two bottom options named "allow to reroute audio from device to the car" & "allow permissions for handling phone calls."
Are there any permissions i need to grant to the phone app itself or the android auto app to get this to work?
