{
    GranteePrincipal = "arn:aws:iam::111122223333:role/ExampleRole", // The identity that is given permission to perform the operations specified in the grant.
    KeyId = "arn:aws:kms:us-east-2:444455556666:key/1234abcd-12ab-34cd-56ef-1234567890ab", // The identifier of the CMK to which the grant applies. You can use the key ID or the Amazon Resource Name (ARN) of the CMK.
    Operations = new List {
