User not able to add user

AADSTS50105: Your administrator has configured the application Box ('ebebd342-cf9e-4559-b383-6519e33d08e9') to block users unless they are specifically granted ('assigned') access to the application. The signed in user 'information redacted' is blocked because they are not a direct member of a group with access, nor had access directly assigned by an administrator. Please contact your administrator to assign access to this application.
