how to set Service Group for Service Mesh in UI

[devaDong]

Skywalking v 9.0.0
I want to observe Service Mesh in Skywalking, But I don't know where to set Service Group for Service Mesh?
After several rounds of searching for Skywalking's official website, I still can't find it.

Isn't the doc right in place? https://skywalking.apache.org/docs/main/next/en/setup/backend/service-auto-grouping/

First doc of setup. Don't know what you mean can't find it. Have you ever read the whole doc?

I know this place . https://skywalking.apache.org/docs/main/next/en/setup/backend/service-auto-grouping/
I have already set the group for normal Service. But it doesn't seem to work for the Service Mesh.
In this place(https://skywalking.apache.org/docs/main/next/en/setup/envoy/metrics_service_setting/ ) ,there is no suitable parameter to set the Group Name and Service Name for Data Plane.

If it is about service mesh in practice, check the showcase setup. It is there.
