It is possible to launch the RC app and initiate actions via uri schemes (https://developers.ringcentral.com/guide/basics/uri-schemes). E.g. it is possible to initiate a phone call from via a link in a web page.

Is it possible to start a video call via such uri scheme?

It should launch the rcapp and behave just like clicking the "Start video call" button on a contact profile - ringing that contact for a video call.

This would allow our users to launch video calls from a web page, without looking up contact information in the RC app.
