Can't get golden stats from linkerd Prometheus? (Querying Prometheus for latency and success rate)

[MA3CIN]

I'm trying to access the golden metrics per deployment (or per service) via prometheus. With linkerd viz stat these stats are easy to achieve:

For latency i know that i can divide response_latency_ms_sum by response_latency_ms_count. But what about the Success rate? I can't seem to access these metrics.

Apparently viz even calls Prometheus to access these metrics:
#12583 , https://github.com/linkerd/linkerd2/blob/main/web/main.go#L31 https://github.com/linkerd/linkerd2/blob/main/viz/metrics-api/cmd/main.go#L27
But I can only find partial queries by investigating the source code.

Has anyone had any success in getting exactly these metrics ( Latency P50, P95, 99, and Success rate) via Prometheus?
