with-auth0 example does not work

[mwarger]

Describe the bug After filling in the information, the with-auth0 example always results in an 'Access Denied' error.

To Reproduce Steps to reproduce the behavior:

• Create an auth0 single page application and fill in the correct information in the example code (auth0ClientId and authorizationEndpoint). Continue following the instructions in the README for the example.
• Run the example and attempt to login with either email or google authentication.
• See that access is denied.

Expected behavior I would expect the authentication flow to work after following the instructions.

Smartphone (please complete the following information):
