Allow Jitsi-meet to be accessible from iframe on specific domain only

I’ve set up a jitsi-meet server (Apache2).

I have another web application where employees of our organisation are registered. I want only them to use my server resources. So, I used iFrame in that web application for jitsi-meet as described at

By default, Jitsi-Meet allows anyone to start a new meeting by accessing the domain root.

Is it possible to restrict access to jitsi-meet only from the iframe on specific domain? Not even accessible by directly visiting the installation domain?

@Milind_Sharma Did you get any solution on this?
