CLI option to open the calendar

Hello,

Is there a CLI option to open the calendar?  I cannot find it. [1]

I would prefere something like:
thunderbird -calendar

Or something like:
thunderbird -extension lightning

What I want is starting the calendar from the Gnome menu. I can set
Thunderbird as default application now. Thunderbird opens but not on the
calendar tab.

With regards,
Paul van der Vlis.
