[KDE Connect] Issues with pointer in slideshow remote not showing on external monitor

I have a big presentation coming up, and this is the first time using Linux and Libreoffice for this. I've been using KDE Connect for a long time for many different use cases, but never tested the slideshow remote before now. It works as expected on KDE 6 with Wayland, except for the pointer.

The pointer will only show on my laptop screen, and not on my external monitor. This is naturally where I will show the presentation, so this is where I would want the pointer to show. This is the case regardless of which display is set to be the primary monitor. Screen are set to "Unify outputs".

I found this post explaining the exact same issue from 2020, but there was never a solution to this.

Has anyone run into the same issue and know of a way to get this working?
