Is there a way to publish a teams calendar?

Hi, I was wondering if anyone knows of a simple way to publish a teams calendar?

I have set teams up for various activities in our church like in this screenshot

The calendars from these appear in the outlook of everyone in the team like this

But when I try to publish this to give wider visibility (and we don't want all the details available to everyone) it doesn't appear in the list.

Does anyone know how to do this?

Thanks for any help.
