Username/password authentication does not seem to work?

Hi,
For my internship, I need to make postman tests to test the application in an Azure devops pipeline.
I want to log in with username and password and receive a token from auth0 without using the web interface. I found this https://auth0.com/docs/login/embedded-login/cross-origin-authentication, but I am not able to get it to work. When I try this endpoint co/authenticate I get this:

Then I tried it with this endpoint oauth/token and I get this:

For both, I use a Regular Web Application and I enabled password grand type for it.

And I want to be able to do the same thing but then for a user. Is this possible and how?
