Required App Permissions

Permissions for Service provisioning

When using Microsoft PowerShell to provision new Nimbus services, the following permissions are granted automatically:

Component	When are permissions granted	Purpose
Nimbus App	on each run of the script	Retrieves information about MS Teams users, their team memberships and roles, group memberships
Calling Bot	on each run of the script	Responsible for the team calls (regardless of team/workflow configuration)
Media Bot	on each run of the script	Allows to make Voice Message recordings
Chat Bot	in User Preferences (Portal) once by the user to register with the bot. No additional permissions are needed.	Relay service-related chat messages via adaptive cards.

If not already granted by a Tenant administrator additional Required User Permissions may requested from each service user individually upon first login to Nimbus. Not granting these permissions may affect internal user search fields such as the one in Attendant Console.

The Microsoft.Graph.* modules which are used by the Provisioning Script require permissions that need to be granted for the Microsoft Graph PowerShell Enterprise application:

User.Read.All	Application	Tenant Admin - Nimbus App User - Nimbus UI	yes	yes	yes	-	yes	-	Nimbus App - Get CallerInformation Nimbus UI - Full Search Users Interact - Get CallerInformation Why is this necessary? Nimbus reads the complete profile of all users to determine group memberships within the organization. Nimbus needs this information to correctly identify users via search (→ also see "Covered Search Fields" chapter below). The presence status of MS Teams users is also determined this way, which is used for call distribution. Note: Nimbus does *not* store any of the exchanged data. The permissions are primarily used to display live data during daily usage of the product.

Covered Search Fields

Nimbus uses User.Read.All permissions to cover the following search fields. The sources searched are:

Nimbus internal Address Books.
Your O365 Tenant Directory.
Exchange (individual user Address books). If not granted by the Tenant Admin, User Permissions need to be granted individually.

Fields covered by Nimbus user search

Searchable Fields and Filters	Nimbus Address Book	O365 Tenant Directory	Exchange (User Address Book)	Notes
Display Name				KNOWN LIMITATION The search covers the predefined Nimbus Address Books fields, but no custom-fields can currently be searched. We are working to gradually alleviate this situation and make the search experience more consistent. Fields are supported by search. Fields additionally support "CONTAINS" as search operator. Example: Searching for 'cha' will not only find 'Chadwick' but also 'Michael' These fields support Filter capabilities which can be used to narrow down a contact search in Attendant Console. User.Read.All permissions must be granted to use this feature. As a Tenant Admin, head to the Nimbus Portal > User Preferences > Permissions "Tab" > Advanced Search and manage consent for your entire tenant.
