Is there a way to start a session from the command line?

Hi,

I use neovim 0.6.1, on Ubuntu.
Is there a way to directly open a Startify session from the command line, as in:
$ nvim --open-startify-session my_project_session

I assume it's a lot more complicated than that, but I just need something that I could make a zsh macro out of.
Inelegant hacks are welcome.
