Sagemaker cross-account deployments

I am trying to setup an aws code pipeline project that will deploy a sagemaker model from a model registry cross-account from our qa account.

The plan is to deploy the latest approval model from the registry . I followed steps https://docs.aws.amazon.com/sagemaker/latest/dg/model-registry-deploy.html#model-registry-deploy-xaccount but the code below fails when trying to find the latest approved model to deploy. Is their another API endpoint that allows me to look up by ARN instead of using list_model_package_groups?

# try to find the latest approved model package from  model registry from our dev/qa VPC 
groups = self.sm.list_model_package_groups(NameContains=self.model_package, SortOrder='Descending')
most_recent_group = groups['ModelPackageGroupSummaryList'][0]
packages = self.sm.list_model_packages(ModelPackageGroupName=most_recent_group['ModelPackageGroupName'],
                                       SortOrder='Descending', ModelApprovalStatus='Approved')
most_recent_packages = packages['ModelPackageSummaryList']
most_recent_package = most_recent_packages[0]
model_name = '-'.join(most_recent_package['ModelPackageArn'].split('/')[-2:])
model_package_arn = most_recent_package['ModelPackageArn']
container_list = [{'ModelPackageName': model_package_arn}]
self.sm.create_model(
    ModelName=model_name,
    ExecutionRoleArn=self.role,
    Containers=container_list
)
return model_name
