Mentafy needs access to a project folder on the user’s Onedrive cloud storage in order to access the automatically saved version history and other file uploads / changes.
For security reasons, by default the users will not be able to grant this permission themselves, unless the administrator has configured this in general for all apps or for Mentafy specifically.
This special link will grant all Microsoft permissions Mentafy ever requires (full Mentafy and import - users will not get prompted to accept the permissions request individually): https://login.microsoftonline.com/organizations/adminconsent?client_id=cb89aab0-b687-4d59-9699-36ec76abbd4b - click “Accept”:

N.B.: The user with administrator privileges can also grant fewer permissions for the whole organization while giving them for herself ("Consent on behalf of your organization" checkbox).
Go to User Consent Settings in Azure [https://portal.azure.com/#view/Microsoft_AAD_IAM/ConsentPoliciesMenuBlade/~/UserSettings]
Choose a Consent Policy Option
Option 1: Allow user consent for apps → Users can freely sign up for Mentafy on their own.
Option 2 (Recommended): Allow user consent for apps from verified publishers, for selected permissions. → This works because, Mentafy is a verified publisher, but you'll need to allow specific permissions manually (see below).

The recommended option provides better security while still allowing access to Mentafy.

files.readwrite is located under the Microsoft Graph API and can be hard to find.

You can create a free personal Microsoft account and use it with Mentafy. In this scenario the users can grant permissions as required on their own behalf.
