port forwarding and RDP or ssh

[Alex]

Hi, I have a fedora38 system on Optonline with port 1024 forwarded from the
router to 1024 on the fedora38 system where ssh is listening. I'm currently
using the following to connect:

$ ssh -i ~/.ssh/mykey-key.rsa -L 5901:127.0.0.1:5901 -Y -l gary remotehost
-p 1024

I'd like to be able to have applications launched on the remote system
appear on my desktop, also using fedora38. What's the best way to do that?

I've read about RDP and gnome-remote-session but much of the docs appear to
be out-of-date. General advice on what works in 2024 would be appreciated.

My friend is having difficulty with his evolution configuration. I'd like
to be able to launch evolution on his PC and have it appear on mine.
