Kde connect: no remote keyboard to desktop machine

I have three devices (desktop, laptop, phone), all using KDE connect. Remote mouse input works fine, but I cannot send keyboard inputs to the desktop machine. I can send keyboard inputs from the desktop to the laptop and from phone to laptop, but not to the desktop from either device.

The “remote input” GUI on the laptop is missing an input field to put text in. The phone app’s keyboard input to the desktop is ignored.

The relevant KDE connect settings for remote input are all selected (on both laptop and desktop).

According to this comment, I need KDE connect version 23.04.
The laptop using Fedora 38 fulfills that version requirement - and remote keyboard works there - while the desktop using Fedora 37 is only on version 22.12.
