How can I request an Access Token in Postman against an Azure AD B2C tenant?

new access token screenshot

I tried taking the url from Run Now in the Azure portal and putting that in the Auth Url but that produces the following error:

b2c error

Update

Following Chris's answer, I'm now past the above error. I'm able to sign-in but still can't get an access token:

AADB2C90085: The service has encountered an internal error. Please reauthenticate and try again. Correlation ID: 45c56d47-4739-465f-8e02-49ba5b3a1b86 Timestamp: 2017-11-16 15:27:52Z

Using @Chris Padgett's answer, I was able to get it working using the Implicit Grant Type (couldn't get it working w/ Authorization Code Gran Type).

Grant Type: Implicit

Callback URL: any URL defined in my B2C app

Auth URL: https://login.microsoftonline.com/te/{tenant}/{policy}/oauth2/v2.0/authorize

Client ID: Application ID from my B2C app

Scope: https://{tenant}.onmicrosoft.com/{web api app id uri}/{scope name}

Client Authentication: Either one, it didn't matter
