Defender ATP Onboarding Package Deployment

I've downloaded and extracted the onboarding package (Microsoft Endpoint Configuration Manager current branch and later) and am trying to create a Microsoft Defender ATP Policy. In the policy wizard when selecting the Configuration File, I am left with the following in the screenshot. The Workspace Key and Workspace Id aren't populating and I'm not sure where to find this information. In fact, I created a previous papckage awhile back and do not remember being prompted for a Key/Id. Endpoint Configuration Manager version is 2002.
