Import ICS in Google Calendar add-on

Hi all!

I create some ICS files containing Zoom meeting details. I send them to Gmail accounts having the Zoom for Google Workspace add-on installed, and I want the add-on to display the details nicely, just like when I create an event from the add-on.

What do I need to include in the ICS file to do this? I tried with the -::~:~::~:~:~:~:~:~:~:~:~:~ delimiters in the description but it doesn't work.

I manage to do it for Outlook for example, if my ICS has a proper description, the Outlook add-on displays a "Join" button. I want kind of the same for Google Calendar.

Thanks for your help!
