Cloud Kicks has a team of product owners that need a space to share feedback and ideas with just the product team. How should the administrator leverage Salesforce to help the team collaborate?

Activity History logs interactions related to records (like tasks or calls) but is not designed as a dynamic, team-wide collaboration forum for sharing ideas.

A Chatter Private Group restricts visibility and participation to only invited members, ensuring that feedback and ideas shared are confidential and accessible exclusively by the product team, fulfilling the requirement for a private collaboration space.

A Chatter Public Group allows all users in the organization to view and post, which would not meet the requirement to limit sharing to 'just the product team'.

Quick Actions are shortcuts for performing common tasks or creating records, not a dedicated platform for team collaboration and discussion.
