Assuming you would like a tutorial on how to add an application to Launchpad in macOS:
Launchpad is a feature in macOS that displays all of your installed apps in one place. To add an app to Launchpad, first open Finder and locate the app you want to add. Once you have found the app, right-click (or Control+click) on it and select Get Info from the menu that appears. In the window that opens, check the box next to Application Category and choose Utilities from the drop-down menu. Then close the Get Info window.
Next, open Launchpad by clicking its icon in the Dock or by searching for it with Spotlight. You should see your app in Launchpad now. If not, click anywhere inside Launchpad and press F5 on your keyboard to refresh the view.
