How grafana determines profile type ？

I sampled the heap memory information of a Java program through async-profiler and uploaded it to pyroscope through HTTP. The following is the uploaded code:

func main() {
    pyroscopeServer := "http://localhost:4040"
    applicationName := fmt.Sprintf("kante-test-test-sg{lang=java,env=test}")

    // Pprof file path
    pprofFilePath := fmt.Sprintf("/Users/kante.yang/pprof/java-propf")

    flameGraphData, err := fileutils.ReadFile(pprofFilePath)

    // Pyroscope URL
    pyroscopeURL := fmt.Sprintf("%s/ingest?name=%s", pyroscopeServer, applicationName)
    fmt.Println(applicationName)
    fmt.Println(pyroscopeURL)

    // Create the HTTP request
    req, err := createPythonJavaReq(flameGraphData, pyroscopeURL)
    if err != nil {
        fmt.Println("Error creating request:", err)
        return
    }

    // Send the request
    client := &http.Client{Timeout: 10 * time.Second}
    resp, err := client.Do(req)
    defer resp.Body.Close()
    if err != nil {
        fmt.Println("Error sending request:", err)
        return
    }

    // Check the response status
    if resp.StatusCode == http.StatusOK {
        fmt.Println("Profile data successfully sent to Pyroscope.")
    } else {
        fmt.Printf("Failed to send data. Status code: %d, Message: %s\n", resp.StatusCode, resp.Status)
    }
}

func createPythonJavaReq(rawProfileData []byte, url string) (*http.Request, error) {
    req, err := http.NewRequest("POST", url, bytes.NewBuffer(rawProfileData))
    if err != nil {
        return nil, errors.Wrap(err, "create pyroscope request error")
    }
    req.Header.Set("Content-Type", "application/octet-stream")

    return req, nil
}

I originally thought that pyroscope would automatically parse the format of the data. In fact, it did this for the data generated by pprof. However, after this data was uploaded to pyroscope, it was parsed into cpu, as shown below:

I'm not sure why this happens, or can I specify the profiletype when uploading data using the http api?

I use this command to generate java profile data: profiler.sh -o collapsed -e allocs
