Hello everyone,
When I send a POST request to get a refreshable token for Power BI REST API I get the following error:
{
"error": "invalid_grant",
"error_description": "AADSTS50126: Error validating credentials due to invalid username or password.\r\nTrace ID: 99c45d79-6d9d-4e29-8aa8-912e47e65e00\r\nCorrelation ID: bb95c25d-0f3c-4212-9502-95f16703f035\r\nTimestamp: 2021-03-08 10:09:56Z",
"error_codes": [
50126
],
"timestamp": "2021-03-08 10:09:56Z",
"trace_id": "99c45d79-6d9d-4e29-8aa8-912e47e65e00",
"correlation_id": "bb95c25d-0f3c-4212-9502-95f16703f035",
"error_uri": "https://login.microsoftonline.com/error?code=50126"
}
This is what I did :
I am only a user in the Azure Portal
The Global Admin registered an app from here: dev.powerbi.com/Apps
I gave it all the read authorizations
He made me Owner of that app
He created a client secret for that app
We added Tenant.Read.All permission and granted it to my organization
Now I am using POSTMAN to generate a refreshable token but I get the error you see above (I checked my email and password several times, see postman's config below)

Thanks in advance.
