Make sure you apply the appropriate viewing permissions when uploading a video. Permissions at the video level allow you to control who can see your video, who can own and edit it and assign access from within groups and channels. When you upload a video into Stream, you have the option to select, Allow everyone in your company to view this video. Any users with an ECU Microsoft 365 account can see the video and add it to their groups and/or channels. The Shared with field is where you select who can view/own your video and in which groups/channels. Use the drop-down to search and select viewers.
Recordings can be uploaded to Mediasite or Studio to maintain a repository for future use.
