docs: Calls oauth/token endpoint with password-realm grant type
  
  
          This is the OAuth 2.0 grant that highly trusted apps utilize in order
          to access an API. In this flow the end-user is asked to fill in credentials
          (username/password) typically using an interactive form in the user-agent
          (browser). This information is later on sent to the client and Auth0.
          It is therefore imperative that the client is absolutely trusted with
          this information.
  
          Args:
              grant_type (str): Denotes the flow you're using. For password realm
              use http://auth0.com/oauth/grant-type/password-realm
  
              client_id (str): your application's client Id
  
              client_secret (str): your application's client Secret
  
              audience (str): The unique identifier of the target API you want to access.
  
              username (str): Resource owner's identifier
  
              password (str): resource owner's Secret
  
              scope(str): String value of the different scopes the client is asking for.
              Multiple scopes are separated with whitespace.
  
              realm (str): String value of the realm the user belongs.
              Set this if you want to add realm support at this grant.
  
          Returns:
              access_token, id_token
