After connecting your RingCentral integration, our integration already supports RC Video.
If you want to generate RingCentral Video links or RingCentral Meet links, this would be determined whether your actual RingCentral account is upgraded to RC Videos
Note that, This upgrade happens from the RingCentral side.
FreeBusy defers to your RC account and asks it whether it should ask for RC Meetings or RC Video links. It is that simple and straightforward!
