Calendar/Scheduling software/apps and Zoom

Hello, hoping to get a little clarity on whether there is a Zoom login that we get with RingCentral? Specifically I am hoping to use Calendly or x.ai for scheduling meetings, and they have Zoom integrations I was wanting to leverage. I see that Zapier can do Calendly, although I'd prefer not to use a 3rd party service if not needed. Is there a way that the Zoom direct integration transfers to us using RingCentral?
