Choose the permission or permissions marked as least privileged for this API. Use a higher privileged permission or permissions only if your app requires it. For details about delegated and application permissions, see Permission types. To learn more about these permissions, see the permissions reference.

Important
In delegated scenarios with work or school accounts, the admin must be assigned a supported Microsoft Entra role or a custom role with a supported role permission. The following least privileged roles are supported for this operation:
You can specify the following properties when creating a customAuthenticationExtension. You must specify the @odata.type property with a value of the customAuthenticationExtension object type that you want to create. For example, to create an onTokenIssuanceStartCustomExtension object, set @odata.type to #microsoft.graph.onTokenIssuanceStartCustomExtension.
Collection of claims to be returned by the API called by this custom authentication extension. Can be set for onTokenIssuanceStartCustomExtension object only. Used to populate claims mapping experience in Microsoft Entra admin center. Optional.
