@[email protected] You can't log into other Fediverse services using your Lemmy account. It's a Lemmy account for your specific Lemmy instance and doesn't work anywhere else.
What you can do is talk to people on other Fediverse services with your Lemmy account on your instance in the same way you are communicating with people from other Lemmy instances.
For example, the op you are replying to is using Friendica, you are using Lemmy and I am using Firefish right now.

You can drag & drop files on the popup from the KDE Connect tray icon to send to the phone.
The popup opens either when clicking on the tray icon or when hovering over it while dragging a file.
Keyboard to phone needs to be setup on the phone.
When you open the app at the bottom it lists plugins that need permission to work.
Follow the setup for "Receive remote keypresses" to add KDE Connect as an input method.
Whenever KDE Connect is active as a keyboard, an input box appears in the KDE Connect popup on the desktop for you to type in.
I'm pretty sure it's not wayland only. I can't see why it would be.
