AWS S3 GetObject error on cross account access - amazon-web-services

Question

I am the owner of AWS AccountC and need List and Get Permissions to BucketName owned by another person/team.
The bucket policy created is attached below. Policy for AccountA and AccountB were already existing and I added the policy for AccountC as given below
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "AccessA",
"Effect": "Allow",
"Principal": {
"AWS": [
"arn:aws:iam::AccountA:root",
"arn:aws:iam::AccountA:user/ABC-Prod"
]
},
"Action": [
"s3:GetObject",
"s3:List*"
],
"Resource": [
"arn:aws:s3:::BucketName/*",
"arn:aws:s3:::BucketName"
]
},
{
"Sid": "AccessB",
"Effect": "Allow",
"Principal": {
"AWS": [
"arn:aws:iam::AccountB:user/service-user",
"arn:aws:iam::AccountB:role/BatchUserRole"
]
},
"Action": "*",
"Resource": [
"arn:aws:s3:::BucketName/*",
"arn:aws:s3:::BucketName"
]
},
{
"Sid": "AccessC",
"Effect": "Allow",
"Principal": {
"AWS": "arn:aws:iam::AccountC:root"
},
"Action": "s3:List*",
"Resource": "arn:aws:s3:::BucketName"
},
{
"Sid": "AccessD",
"Effect": "Allow",
"Principal": {
"AWS": "arn:aws:iam::AccountC:root"
},
"Action": "s3:Get*",
"Resource": "arn:aws:s3:::BucketName/*"
}
]
}
I am able to list contents of BucketName using
aws s3 ls BucketName.
However, when I try
aws s3 cp --recursive BucketName/folderName/ ., it gives me an Access Denied error
An error occurred (AccessDenied) when calling the GetObject operation: Access Denied
Block public access is enabled on the bucket, however I believe it should not affect since the Bucket policy is added
Tried multiple way to write the policy but the error persists. Can someone please help me understand what I might be missing here? Would be really grateful
