Open new session in group with a new pane - Simple?

[bearcatsandor]

I want to run a tmux config that will do the following when I open alacritty:

1. Start a new session in the group "moonwind"
2. Create a new window(pane) in that session

So in effect I have multiple terminals open on my screen, but they all contain the same group of panes, but each one opens a new window. It looks like separate terminal sessions, but it's not. So it would be doing a tmux new-session -t 'moonwind' and then a tmux new-window on that session unless it's the first one.

I've been hammering at my cli for the last day trying to accomplish this via tmux commands and failing, only to come across tmuxp this morning.

Could I accomplish this with a tmuxp configuration?

Thank you
