@dgutride Just a question here, the logic we have in place is using startsWith, just in case we have multiple csv that have the same prefix. I don't know wether we wanna add support from the Openshift ECK operator elasticsearch-operator too, in that case we might wanna change the csvName

[dgutride]

The name is on this line in their repo: https://github.com/elastic/cloud-on-k8s/blob/8270ad0ae9aebbc39a31fede2c2eb90def222d5b/hack/operatorhub/config.yaml#L42

Tested in cluster, added the operator and it appears in the enabled page.
