At this point, I have assigned the public files read-policy that allows the authenticated users to access the /public-files folder in the bucket.

You can upload a file in the /public-files folder to verify that the policy is working as expected.

Reload the page and click on the List Public Files button to fetch the list.

If you try to do the List My Files, it will throw an Access Denied error because we are yet to attach the per-user access policy.
