I have been trying for weeks to download this App to complete the Learn CRM Essentials for Salesforce Classic.

When I try to download it, it wants to download it into our production site.  I want to download it into the Trailhead Playground.

I have tried all the directions that are provided in the module, but nothing is working.

Assistance is needed.

How do I log in to Trailhead to complete installing the app just downloaded to complete App Exchange challenge? Upon download only Production or sandbox is an option, no developer orgs.
