Cross account access to AWS resources

Question

I have access to two AWS accounts, training and staging. Staging account holds all hosted zones, IAM roles; I want to grant access to training account so it can access a resource in Route53. I have created an IAM policy as below:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "route53:ChangeResourceRecordSets"
      ],
      "Resource": [
        "arn:aws:route53:::hostedzone/*"
      ]
    },
    {
      "Effect": "Allow",
      "Action": [
        "route53:ListHostedZones",
        "route53:ListResourceRecordSets"
      ],
      "Resource": [
        "*"
      ]
    }
  ]
}

Then I created an IAM role and attached above policy using "Another AWS account" option inserting training account ID, but I am still not able to list any hosted zones.

I am not sure what exactly I am missing here.
