Can't edit bucket policy in AWS Playground

When i try to add bucket policy. It shows This
" Your bucket policy changes can’t be saved

You either don’t have permissions to edit the bucket policy, or your bucket policy grants a level of public access that conflicts with your Block Public Access settings. To edit a bucket policy, you need the s3:PutBucketPolicy permission.
User: arn:aws:iam::058264295383:user/kk_labs_user_189840 is not authorized to perform: s3:PutBucketPolicy on resource: “arn:aws:s3:::portfolio-akash-v1” with an explicit deny in a service control policy"

I even turned off block public access settings.

This means that this operation is not permitted by playground permissions.

Does this mean we do not have the permission to edit or create bucket policies.?
Can we expect this to be permitted in the future?
