Users do NOT want to give zoom full read and write access to their calendars merely to add an event. I DO NOT normally see prompts like this when trying to add an event to a google calendar with other APIs.
Based on the screenshot, it looks like you’re using the Zoom for GSuite Add-On—is that right? If so, this message will be displayed the first time you use the Add-On:
If you do not wish to allow Zoom access to your Google Suite via this Add-On, you can uninstall this. Zoom does need read/write access in order to add meeting events/details seamlessly as part of this integration.
If you have additional questions about this Add-On, you can also reach out to Zoom Support, as they’re best suited to assist with this functionality.
