Rancher backup Operator

when we install the rancher backup operator , backup operator helm charts only available under the local cluster. But i have 2 separate cluster called production and dev . So after select and go to production cluster’s apps & marketplace section , backup_operator helm chart not visible .

But thing is that same chart repository available under local cluster and production cluster.
chart repository url : https://git.rancher.io/charts branch : release-v2.5

Please let me know , how to integrate backup_operator on production cluster and how to get backup into existent persistent volume.
