Cannot find option for live straeming in setting

Hi @sitinajihah 

Please check your web settings to ensure you have enabled Allow livestreaming of meetings. Once that is enabled, you can start a new meeting and the option should be available in your meeting controls. 

Also, please ensure you are recognized as the host of the meeting. Open the Participants panel and ensure (Host) is next to your name. 

Hope that helps and please make sure to mark the solution as accepted if this information is what you needed.
