Microsoft Azure sign-in authentication - Access Denied

Hi,

We have followed the Odoo documentation:
https://www.odoo.com/documentation/16.0/applications/general/auth/azure.html#microsoft-azure-sign-in-authentication

Then, we got 'access denied' error and the following error in the log:

odoo.addons.auth_oauth.controllers.main: OAuth2: invalid_request
Traceback (most recent call last):
File "/home/odoo/src/odoo/addons/auth_oauth/controllers/main.py", line 134, in signin
db, login, key = env['res.users'].sudo().auth_oauth(provider, kw)
File "/home/odoo/src/odoo/addons/auth_oauth/models/res_users.py", line 124, in auth_oauth
validation = self._auth_oauth_validate(provider, access_token)
File "/home/odoo/src/odoo/addons/auth_oauth/models/res_users.py", line 49, in _auth_oauth_validate
raise Exception(validation['error'])
Exception: invalid_request
