Incoming Calls on Iphone

Not sure if I posting in the right place...

When a colleague calls me on Zoom, I get notified via a window that says who is calling, and also a ringtone on my laptop.

If I am away from my desk, I obviously don't hear the desktop notification and at the moment that same call doesn't come through on my iPhone..

Zoom App is installed, I'm logged in, and notifications are on.

What can I do to get incoming calls on my phone, as well as my laptop? Have had a look around and can't see any answers, not is there an obvious option for this in settings
