How do I setup "Identity-Provider-Initiated Single Sign-On"

I am trying to put an app in the Hubspot marketplace and I’ve already setup the app with Auth0. Hubspot uses a standard Oauth flow is great. What I want is when the user selects to install the app in Hubspot market place it redirects them to an my app, my app redirects to Auth0 which then redirects them to the hubspot screen for selecting an account and granting access WITHOUT the user having to click a Hubspot login button on the Auth0 login page. Is this possible?

This page Identity-Provider-Initiated Single Sign-On describes the idea a bit though I don’t see direction for how to accomplish (I’m not using SAML)
