Create a videos tab in a Teams channel
Feature videos and recordings stored in your team, with the SharePoint Videos page in a channel tab. This is the Stream (on SharePoint) replacement for the Stream (Classic) channel tab in Teams.
By default, this SharePoint Videos page will show the most recent 36 video & recording files uploaded to the document library / Files tabs for your team. You can edit this default page to customize it by changing the web part settings, by adding other web parts, or by adding text to the page to make it your own.
To learn how to setup and customize this Videos page, see the help article: Feature videos in a Teams channel tab
