My Question or Issue

When Setup-Apps-Spotify-Notifications-Play is enabled only then I can see the Spotify player from the Notifications Menu of my phone.

However, also then and only then every time I open a different app like Netflix  or YouTube then Spotify opens this icon on top of the other app. How to disable? See attachment.
