Required permissions to use this tool - nicolonsky/ModernWorkplaceConcierge GitHub Wiki

The Modern Workplace Concierge requires an enterprise application in your Azure AD tenant which asks for the delegated permissions listed on this page. Initially, consent from a global administrator is required (only to register the app).

Afterwards, the app works with delegated permissions which means that all actions are performed on behalf of the signed-in user. Therefore your account needs to have appropriate permissions like an Intune or Conditional Access administrator role.
