CLI 'argocd admin cluster stats' doesn't work with round-robin

Describe the bug

I do not see the statistics correctly when the cluster uses the round robin algorithm.

The application controller works correctly with round robin (at least I can see round robin in logs.) but argocd cli admin cluster stats not.

To Reproduce

• Install argocd
• Config argocd with 3 replicas in application controllers and algorithm of sharding: round-robin
• Login with argocd cli into cluster argocd
• Run: argocd admin cluster stats

Values:

crds:
  install: true
  keep: true

global:
  logging:
    level: debug
  params:
    controller.sharding.algorithm: "round-robin"

controller:
  replicas: 3

Expected behavior

I hope to see the values of shards correctly.

I have been see the code of argocd and I can find the following lines: https://github.com/argoproj/argo-cd/blob/v2.9.3/cmd/argocd/commands/admin/cluster.go#L125C77-L125C101 common.DefaultShardingAlgorithm = LegacyShardingAlgorithm LegacyShardingAlgorithm = "legacy" https://github.com/argoproj/argo-cd/blob/v2.9.3/common/common.go#L118C5-L118C5

does this mean that "admin cluster stats" doesn't work with any other algorithm than "legacy"?

Also, when I have configured the algorithm as legacy, I can see the same information (zero shard, zero apps).

I got the same error.
