Brave browser --> no "media controls" icon for scrubbing


I totally new with macbook pro 13" with touchbar. Can someone please guide me how to enable "Media controls" button from brave browser with BTT? I really like the media scrubbing for youtube, soundcloud, etc... The button is there automatically when I don't use BTT, but I can't figure out how to add/enable it in BTT. I also installed GoldenChaos in hope I could somewhere find the option for it.
