Can't use Shazam when connected via Carplay

I've got an iPhone Xs and use iOS 14.0.1

When my phone is connected via Carplay I can't Shazam a song playing on the car radio. As soon as I start the music recognition the phone apparently invokes a Bluetooth call (or similar) which stops the radio from being heard. This "feature" is not new to iOS 14 but was introduced some time in iOS 13 if I recall correctly.

Ideally Shazam itself would be Carplay enabled, but don't get me wong, I don't play with my cell when driving, but every so often my wife drives while my cell is connected via Carplay and I'd like to know what's playing without dropping off Carplay first ...

Any thoughts?

Best regards
