Are you experiencing the same issue as #2113?

[steel-digit]

No, I can see the plugins options just fine in the menu bar.
The issue is on the TouchBar itself; if I want to control playback on YT Music through the built-in MacOS playback controls on the TouchBar, the icon for the YouTube app is missing on the TouchBar itself. This is used to switch between media apps if you are playing media from different sources (e.g. switch between YT Music and Apple Music).

I've included an image I pulled from Google, on the left of the TouchBar you can see an app icon which I have circled in blue, for YouTube Music this is missing when I use the TouchBar.

I'm starting to wonder if this is a bug or just never implemented correctly.

I see the change has been implemented in the latest release, 3.4.1, but the problem persists. In general the way the media controls work on the TouchBar for this app is lackluster. When I find the time I will log a new issue with a more elaborate problem description and how this feature should be working. @JellyBrick
