Zoom opens Outlook instead of Google Calendar

Hi

I started encountering a strange behavior just after upgrading to premium.

Previously when I used to schedule a meeting from Zoom desktop (Home > Schedule > fill info > Save), Google Calendar would open automatically so I can add the meeting to the calendar.

But now after upgrading to premium and scheduling a meeting in the same procedure, after hitting "Save", Microsoft Outlook opens up instead of Google Calendar. I don't use Microsoft Outlook. How can I revert back to the old behavior?

Thanks in advance
