What is SharePoint app bar

The SharePoint app bar is a little flyout on the left-hand side of all modern SharePoint sites, which looks like this.

SharePoint app bar aims to help users find important content and resources no matter where they are in SharePoint.

You can enable Global Navigation to allow users to easily navigate to your company’s navigation from anywhere in SharePoint. Global Navigation is the only tab that you can customize on the SharePoint app bar. My sites, My news, and My files tabs will update your personalized content on SharePoint.
