To share apps with people, you must first add them as users and invite them to one or more Collections. Users are invited via email and/or SMS. Invited users will receive links to the AppGallery mobile client and to any apps you've shared.
On the AppGallery website, the User section displays all users that have been invited to view your Collections. Each user record contains the user's email and an optional phone number. You can also use this section to add new users one at a time or in bulk by importing them from a spreadsheet. Individual users also can be organized into groups, which can then be added to Collections making it easier to share apps with many people at once.
