Once clicked on, you will be presented with a table labeled "Dashboard Blocks Settings," where you can specify which blocks you would like to appear on your "Dashboard."

For example:
Once you are done selecting the particular blocks and fields to include within your "Dashboard," click "Save," and your settings will be applied.
