Microsoft Teams now allows you to include an existing OneNote notebook as a tab

Microsoft Teams already allowed its users to create a new shared OneNote Notebook via OneNote tab for team collaboration. Now, Microsoft has improved this feature by allowing user to include an existing OneNote notebook as a tab. This means anyone can bring their own OneNote content directly into a channel for further discussion. Here’s how this new experience will  work when you go to OneNote tab in Microsoft Teams.
