Google Calendar to attack self-hosted installation

Is there a way to configure this extension: https://gsuite.google.com/marketplace/app/jitsi_meet_for_google_calendar/421935948107

to point to our self-hosted jitsi-meet setup?

Not at the moment, sorry.

Any plan to add this feature ? Is there an issue to follow somewhere ?
Thanks !

Sorry, no plans for that at the moment.
Seems everybody can subscribe to Google Beta program and do it.
