Adding Stream content is quite simple—in fact, it's very similar to adding a Stream tab to Microsoft Teams. Stream content is displayed in SharePoint using the Stream web part. The Stream web part can display a list of videos from the Stream site (sorted by trending, likes, views, or published date), individual videos, or Stream channels.

To add either a video or a Stream Channel to a SharePoint site, follow these steps:

1. Launch Microsoft Stream (https://web.microsoftstream.com) and navigate to the video or channel that you want to make available in SharePoint Online.
2. Depending on the content you want to share, follow one of these two steps: 
   • If you want to share a channel, select the URL bar text for the Stream channel URL and copy it. 
   • If you want to share a video, select the ellipsis (...) from the action menu for a video on the Channel page and click Share or click the Share icon when viewing a video. Then, click the Copy button.
3. Navigate to the SharePoint site where you want to share the Stream content and click the Edit button to edit the page.
4. In the area where you want to add the Stream content, click the + button to open the Add a new webpart widget. Then, select Stream:

5. Select one of the options that's available (All of Stream, Single video, or Channel). If you're using the All of Stream option, you can enter a search term to filter the results. Otherwise, select the Single video or Channel option and paste the URL you captured earlier.
6. Click Republish to update the page and display the selected Stream content.
