Have preview-tui support tmux 2.x

Good afternoon!

Thank you for this awesome software.

I was wondering if it'd be possible to add support for tmux 2.x in the preview-tui plugin. I'm using nnn extensively on machines where I am not a sudoer and whose os are a bit old (ubuntu 18, centos 8), so it's not a situation where I can bump tmux.

Thanks!

I don't think it's technically feasible.
tmux 3.0 is required for setting environment variables in a new pane.

Oh noo :(
Anyways, thank you for your answer!
