Webinar - Webhook not firing when live session start

[ITNetwork]

When I start a webinar with a practice_session, I receive a "webhook.started" event. Fine.

I would like to receive a new one, "webhook.started" or at least a "webhook.updated" when the client pass it as LIVE from the Zoom webinar UI. The point is, our app must have different behavior at the start of the webinar practice session, then when it goes live.

Is there a way to catch the click of the author when it runs the "Live" session/leave the practice_session to go Live ?

Thanks
