start zoom meeting without host

I want to give my zoom meeting ID and passcode to my friends to use it but don't need me to open the zoom. I have disable waiting room and choose allow participants to join before host and click anytime. but it doesn't work, my friends said I have to open the zoom otherwise screen shows waiting host to start meeting. How can I set in my setting to allow others to use my zoom anytime without my presence (note, it is not a schedule meeting)?
