Is it possible to change titlebar color (flatpak release)

Is it currently possible to change the color of the titlebar?

At present it is white and it looks really annoying in dark mode.

I saw a PR that added the feature for mac, does it work with linux?

It doesn't work with linux. I am not sure if there is a standard way to do that in linux, probably every window manager has its own way of doing this.

Update: The beta release as of writing this post allows for a dark titlebar.
