Enable SSO user authentication for PingFederate using Auth0

Help

I have an application XYZ which needs to use Pingfederate for SSO . I believe that means that Ping Federate is the IDP and application XYZ is the SP .

To do this I have used Auth0> Enterprise Connect > Open ID Connect (since this is what was recommended by the customer who has the ping federate )

Application XYZ is setup in auth0 as a single page application

I have done the setup as mentioned in Connect to OpenID Connect Identity Provider

I have 2 issues :
In the Enterprise Connection > open ID Connect > Login Experience Customization what will be the domain names ? - will it be customer’s ping federate domain name?

When I try test connection , got error -
“error”: “access_denied”,
“error_description”: “unauthorized_client (implicit grant not allowed for this client)”

Please confirm if the grant type ’ implicit’ is to be enabled for the given client id in ping federate

I have progressed on from this error to now getting Invalid request for the call which looks like :

https://sso.abc.com/as/authorization.oauth2?client_id=aaa&scope=openid%20email&response_type=id_token&redirect_uri=https%3A%2F%2Ftr-abc.auth0.com%2Flogin%2Fcallback&prompt=login&response_mode=form_post&nonce=

Error log says
