How to enable bluetooth multimedia control when screen is locked in Plasma?

I have a bluetooth speaker that has multimedia control buttons. So if I press the buttons I can pause media playing, move to next, or previous song. That works fine when the screen is unlocked

However, when the screen locks, I lose that functionality. This is a new KDE Manjaro installation (plasma 5.24.6), and I remember a few weeks ago when I was using plasma 5.24 before re-installing the distro, I could use the Bluetooth multimedia control even when the screen was locked. Is there a setting somewhere I have not enabled?
