Step 20 - Click on the Add permissions button.

Granting admin consent to the permissions

Step 21 - Build the consent URL. The format is the following:

https://login.microsoftonline.com/{tenant_id}/adminconsent?client_id={microsoft_app_id}&state=12345&redirect_uri={redirect_uri}

Replace the {tenant_id} part with the Directory (tenant) ID and the {microsoft_app_id} part with the Application (client) ID from Step 6. Replace {redirect_uri} part with the URI from Step 14.

Step 22 - Copy the previously created consent URL into the browser, then hit enter. Log in with a Teams Service Admin or Global Admin user of the Microsoft Entra tenant where the Teams environment to record resides. Click on the Accept button. The page will redirect to the webpage provided in the Redirect URI setting.
