In addition to the live tour assistance, dedicated to first time users, Monterey also offers more detailed help on all UI elements marked with the green check marker (Image 1 below)
Image 2, below shows the way how to get that additional help information for the
App launcher feature (aka Tile).
Hover the cursor above the
App launchertile (marker 1)
Note the yellow tooltip-like pop-up dialog and click on the
Documentationlink (marker 2)
The browser window showing the help information for the
App launchertile appears (marker 3)
Note - The size and positioning of the browser on image 2 above are defined by hand, for a better screenshot. However, the future, deeper integration with "external" tools like browser will allow setting the tool layout as a user preference.
