Github Repo and Website should indicate support for YTM

I think you are doing the project disservice by not mentioning support for youtube music on the repo or website https://www.googleplaymusicdesktopplayer.com
even if it is only beta. I am a long time user of this app but when I got a new computer I nearly went with https://github.com/steve228uk/YouTube-Music over this app because it doesn't really mention it is supported
