Support for Huawei EMUI 12 audio controller
Just got an EMUI 12 update for my old P30 Pro and they rolled out a new menu audio controller when swiping down on the right side (left side for notifications). It's a shortcut for audio playback settings within the new interface "control panel".
Spotify is supported so I guess it's up to the app developer.
Anyways: Please add support for this future if possible.
