Easily Switch Between Your Salesforce Org and Communities
In Lightning Experience, the App Launcher displays a tile for every published community along with your apps. In Lightning communities, the App Launcher displays a tile for every published community and app but the All Items area and AppExchange link aren't available. Members see only the communities and apps that they’re authorized to see according to their profile or permission sets.
By default, the App Launcher is hidden in existing communities and displayed in new communities. To show or hide the App Launcher for your users, select Hide App Launcher in community header in the Navigation Menu component properties.
To let users see the App Launcher, you must also enable the Show App Launcher in Communities permission in user profiles in Setup.
