### Steps to Reproduce

mqadmin consumerStatus -n 127.0.0.1:10000 -g DEFAULT%GID_ONS_TEST

127.0.0.1:10000 : proxy cluster remoting port
DEFAULT%GID_ONS_TEST : consumer group

### What Did You Expect to See?

cluster proxy should return corrent connected client running info

### What Did You See Instead?

### Additional Context

_No response_

Start with proxy/src/main/java/org/apache/rocketmq/proxy/service/relay/ClusterProxyRelayService.java at the reported line and reproduce the issue with mqadmin consumerStatus against the proxy cluster remoting port. Trace request type 307 and the consumer group lookup. Done means the proxy returns the connected client running information instead of the unsupported-request error.
