Application tiles are created and configured in the Content Manager, which is a tool located in the Site Manager of SAP Build Work Zone. The Content Manager includes various editors that you can use to configure apps, groups, roles, and catalogs. Once configured, the app appears as a tile in the Applications page of your site - a single page that acts as an embedded launchpad. You can also implement custom visualizations for your app tiles, such as Static App Launcher and Dynamic App Launcher.Reference:
