VS Code displays information related to the Source Control View in the Status Bar.
The type of information depends on which branch and repository you have selected in the Source Control View. By default, the Status Bar will show you information related to the west manifest status, given that the extension provides a source control interface for interacting with west. Clicking on the west manifest in the Status Bar will give you an option to select another manifest from a drop-down menu at the top of the screen.
