KDE Connect on Android - Beep every time phone home screen activated

On my desktop PC, I have KDE running on Kubuntu 23.10, with KDE Connect 23.08.1-0ubuntu1 . My OnePlus Nord2 5G is running OxygenOS 13.0 | Andriod 13, with KDE Connect 1.29.0.

I get an annoying beep every time I activate (or close) the home screen. I can stop this beep by disabling notifications, but I don’t seem to be able to find a way of allowing notifications without getting the beep. This means that if I am not to annoy everybody in hearing, I have to forego controlling the media on my PC from my phone.

This is the third phone that I’ve used with this PC and I’ve not had this problem before.

What am I missing?
