How can I use the flamegraph panel(diff profile) with the pyroscope datasource?

explore-profiles doesn’t match my requirement and I need to create a dashboard and show my flame graph connenting with pyroscope datasource in the dashboard template. I have successfully created a dashboard and displayed a flame graph using the pyroscope datasource for a single view. However, I am having trouble when trying to create a diff view. When reading the source code of grafana-pyroscope-datasource, I noticed that there is a “Diff” function mentioned in the test file (grafana/pkg/tsdb/grafana-pyroscope-datasource/pyroscopeClient_test.go at main · grafana/grafana · GitHub), but I couldn’t find its implementation. I’m confused about how to proceed.
