Webinar do we need Jibri

Friends

I am trying to do a webinar using Jitsi . I have hosted it on AWS and use it for our video calls internally with teams.

We are planning to have a webinar for 1 Hour next week and wanted to set it up on Jitsi . How do i do that .

Do i need to install Jibri? Isit required . I see few links when i login to Live Stream and asks for Youtube Key .

Can you please guide me on the same

Thanks
