GrantType Resource Owner Password not allowed

Help
1

I’m using AuthenticationApi Resource Owner Flow for authenticating user as shown in below code.

var result = await
client.GetTokenAsync(new
ResourceOwnerTokenRequest
            {
                ClientId = _auth0Settings.ClientId,
                ClientSecret = _auth0Settings.ClientSecret,
                Audience = _auth0Settings.ApiIdentifier,
                Scope = scope + " all",
                Realm = connection,
                Username = loginViewModel.EmailAddress,          

                Password = loginViewModel.Password,
            });
            var access_token = result.AccessToken;

I was able to get access_token successfully while using old Auth0 account created at 28/05/2017, but while using same code with new Auth0 account + newly created users, I am getting an error:

Grant type ‘http://auth0.com/oauth/grant-type/password-realm’ not allowed for the client.

According to this post, by using Management Api I can add grant-type to given client. But question is how to do so?

Also have in mind that grant types can now also be managed through the Dashboard by going to the client application advanced settings.
