Send email to guests without owners permission

Can someone explain why the app permissions says “send email to guests without owners’ knowledge”?

That permission makes it difficult to convince friends to install Jitsi without a convincing explanation.

Where do you see that text?

In the Jitsi Meet app.

It’s the 12th permission listed at this link:

If you have permission to edit a calendar event the owner of that event has already gave you that ability. When you change it the rest of the participants of that event will be notified. It is standard behavior of the calendar even outside of the app.

Ok thanks.
