Zoom web SDK- allow attendee to wait in the waiting room even if the meeting is not started

Whenever a meeting is not started, an an user tries to join it, I get an error saying meeting is not yet started. I need to either allow him to wait in the waiting room or allow him to start the meeting. How can I achieve this?
I am using zoom web sdk

Hey @mitz.mulgaonkar,

You can turn on join before host.
