Open KDE Connect app on the phone
Press three horizonals lines in top left to get side menu
Select my paired device from list
Select Slideshow remote
Long press the big blue button that says pointer.

On the computer (paired device) I get a popup titled Dr Kongi with text saying something along the lines of KDE Connect has failed. Please report a bug. There is a button for restarting the app or to cancel.
