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.

Start with Startify's session handling and Neovim's command-line options; verify whether the requested startup path is supported. Done means there is a documented, repeatable way to open a named Startify session from a shell such as zsh.
