Plugins not usable within tmux session cmd override

[ConnorWay32]

I followed the advice in the readme for having preview-tui show up in the picker window, by setting the command to tmux new-session nnn -P<plugin key>, but found that no plugins were showing up when I pressed p. Using NNN's command prompt, I tried echo $NNN_PLUG, but that returned a blank value. The same command returns the correct value when using the default cmd for the picker.
which nnn returned the same address in both cases. The tmux override command returned the same empty environment variable and address whether Neovim was running inside a tmux session or not.

preview-tui and other plugins worked correctly when using nnn from the terminal, nnn with the default picker cmd, nnn inside a tmux session inside a ToggleTerm floating window, and nnn inside a tmux session inside a tmux floating window.

Well you just need to make sure NNN_PLUG is exported in the tmux environment. I set environment variables in my ~/.(z)profile, that works.

Thanks, that worked.
