New Microsoft 365 Lists entry point in the SharePoint app bar

This new feature will allow users to be able to easily access and view Microsoft 365 Lists from the SharePoint app bar that have been followed and viewed often. In the Lists panel, users will be able to select the label to navigate to the Microsoft 365 Lists app. Additionally, users will be able to select the breadcrumb where they’ll navigate to the SharePoint site where the List is located.

Lists that belong to an individual person and have not been shared with others will not be accessible.?

What you need to do to prepare:

You do not need to do anything to prepare. M365 Lists cannot be disabled or customized. If you have not already enabled and customized global navigation in the SharePoint app bar, it’s highly recommended that you do to take advantage of the best navigational experience for end users.
