Zoom meeting links not generating in emails or in calendar

I'm having an issue with Zoom which I have integrated into my CRM. I'm able to have meetings booked successfully but it's not generating meeting links anywhere so neither I nor the client is actually able to hop on the call - we only see that a call is booked in our calendars.

The CRM I'm using is called Clixlo - it's identical to Go High Level.

Any ideas?

Thank you
