I have two different monitors in my setup. On both monitor, I want to be able to open on each monitor a Linux terminal session and start tmux in both. Now I can do separate work on each monitor but switching between those windows is a little bit annoying. So how can I connect this two different tmux sessions, so I can still have two separate terminals on both screens but be able to switch between them with tmux commands?

So I already tried some stuff but all of these approaches just mirrored my tmux sesion in two terminal but I want them to be joined.
