A Global Admin in Office 365 must approve the application in your tenant.
The administrator logs in at https://portal.haldor.se.
When you as a Global Admin log in to the portal for the first time, you must approve the portal. This is to enable it to obtain basic information about you and the tenant.
When this is done, you can access the portal and register as a customer. Enter correct contact information to facilitate support later.
When you are registered as a customer, the service "Haldor Plagiarism Checker" must be approved. This is done under "Services". Click here on "Consent". When you get the box to sign in again, log in with the same account (assuming you are a global admin).
After logging in again, a new approval box will pop up. This time for integration.
The technical description of why these rights are needed is described in the document "Haldor Plagiarism Checker - Technical structure and impact on customer data".
After approval of these rights, the administrative part is complete.
Staff at the school can now install "Haldor Plagiarism Checker" in their Teams.
