How to increase S3 storage for account displays 100% usage in storage lens

I use S3 to store video records from Twilio Services using the I AM account After storing some objects it stopped receiving any new objects and displays in Storage Lens that it uses 100% of its storage (258.2 MB) (271 objects) Here is the policy for I AM account

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "UploadUserDenyEverything",
            "Effect": "Deny",
            "NotAction": "*",
            "Resource": "*"
        },
        {
            "Sid": "UploadUserAllowPutObject",
            "Effect": "Allow",
            "Action": [
                "s3:PutObject"
            ],
            "Resource": [
                "arn:aws:s3:::bucketname/folder/*"
            ],
            "Condition": {
                "StringEquals": {
                    "s3:x-amz-acl": [
                        "public-read"
                    ]
                }
            }
        }
    ]
}

I got this error in twilio error log

Access denied to external S3 bucket configured in recording settings: Access denied to external S3 bucket configured in recording settings. Review your account's recording settings. The media will not be uploaded until the configuration has been fixed.

Any help would be appreciated.
