Which API can we use to check if the host has joined a meeting before joining it iOS Mobile SDK?

Which API can we use to check if the host has joined a meeting before joining it ?
I do not want the user to keep on waiting on the screen with Popup saying “The conference has not yet started. If you are the host then please authenticate. Otherwise, please wait for the host to arrive.”, the user should wait on the screen like a guest in the lobby.
How can i check for this step before joining the meeting ?

That pop-up only shows up before the host joins the meeting. Once the host is in the room, guests just get a prompt to request access and they wait in the lobby till they’re accepted by the host.

Is there a way to check if the host has joined, before joining the call ?
