Hey! I used to have the option to share my screen (stream) into my Facebook personal account. I can no longer see this option.How can I unlock it?Is there a trick or is this option no longer available?

I have recently added my account as multi-user and tried to access the experience 360 videos but there is no "play" button, It just show me the review and other information about the video. Is there a way to enable this feature?
