S3 policy - Transfer Family SFTP

Have you tried setting up the policy as follows ? :

{ "Version":"2012-10-17", "Statement": [ { "Sid": "List", "Action": ["s3:ListBucket"], "Effect": "Allow", "Resource": ["arn:aws:s3:::bucket"] }, { "Sid": "AllowAllS3ActionsInUserFolder", "Effect": "Allow", "Action": ["s3:GetObject"], "Resource": ["arn:aws:s3:::bucket/home/filename.txt"] } ] }
