Need to understand user integration for Partner users

Summary:

We are trying to set up the Partner users in Oracle CPQ. We are using the Salesforce CRM.

We have created a partner organization and we have created few users in it. Now under each user i see "User Integration". If i click the user integration it navigates to the page to generate token based on CRM details. Should i need to provide the CRM details of "Community Users" from SF. Or do we need to enable any additional settings in the CPQ.
