OS: Parrot OS on KDE

GPMDP Version: 4.7.1

Issue Descriptions: KDE has a "media center" where you can manage audio and media, a bit like Windows 10 has. Other audio players show up there and I am able to use the shortcuts like next song, play/pause, etc. But GPMDP does not appear there for some reason, so the shortcuts don't work.

Steps to Reproduce: Open GPDM and play music on KDE, it should appear on the media centre, but does not.
