Install and Uninstall Extensions in Business Central
You can change Business Central by installing extensions that, for example, add functionality, changes behavior, or gives you access to new online services. For more information, see Customizing Business Central Using Extensions.
[!NOTE] To install or uninstall extensions from AppSource or add per-tenant extensions, you must have the right permissions. You must either be a member of the EXTEND. MGT. - ADMIN user group or you must have the EXTEND. MGT. - ADMIN permission set. If you are an administrator, you can assign user groups and permissions to other users in your company.
To use the functionality that is provided by an extension, such as opening pages, running reports, selecting actions, and so on, you must be assigned the permission sets that are installed as part of the extension.
[!NOTE]
The EXTEND. MGT. - ADMIN permission set was introduced in Business Central 2021 release wave 1 as a replacement for the D365 EXTENSION MGT permission set in earlier versions.
