Multiple-select - counting

Are you using our SaaS platform (Baserow.io) or self-hosting Baserow?

SaaS

What do you need help with?

How can I calculated the items in a multi-select-field?
I would like to add a column (field) with this count.

(this is a simple screenshot from Google Sheet to show want I want)

Please attach screenshots or videos if they help illustrate your question.

I also saw this doc (https://baserow.io/user-docs/count-field) and I am (as a newbie) wondering how the field Project Team is populated. I think the names are selected from another table and with the count function, I can get the same result as my question above.
But how to select the names from another table in the Application Builder?
