Just like a Microsoft site, let people request access. If needing to opt-in per video (e.g. if video intentionally private in a more public view and not wanting to entertain access requests). It drives me nuts people having to email me. One of the most powerful features is the access control around the videos which we don't have with SharePoint videos and I just can't get there with MS Stream. Please help my mental sanity. Really love the service otherwise, great way to host videos and search non-industry-jargon terms too.
