Brave Desktop Apps Icons on Taskbar

Hello,
i spend a lot of time on the internet to search a solution but i didn’t found a solution ^^.
So how i get the desktop icons again on linux like on the picture?
I installed brave on a virtual machine to test the youtube music desktop icon and it works without problems. It works for my hosts system too but i think changed something in the settings, but i can’t figure out.
I hope you someone can help me :slight_smile:
