Chrome does not show up in app list in plugin dropdown

Chrome playing audio does not show up in the plugin dropdown, nor it's listed in Properties -> Media Players -> Known Media Players.

Chrome has MPRIS capabilites, following command works

dbus-send --session --print-reply --dest=org.mpris.MediaPlayer2.chromium.instance9640 /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.PlayPause

Using xfce4-pulseaudio-plugin 0.4.3 on Debian 11
