Flaky Tests not getting reported

Hi,
I am not able to get the Flaky Test Report, I uploaded test reports with both Passed and Failed for same test manually.
But it is not reported as Flaky, please help me to resolve this issue.

I have attached the xml and the workflow too

Single Test Failure:

<testcase name="testButtonClickAdd" classname="net.yasik.sampleuitest.ExampleInstrumentedTest" time="1.438" />
<testcase name="testButtonClickSubtract" classname="net.yasik.sampleuitest.ExampleInstrumentedTest" time="2.06" >
    <failure>androidx.test.espresso.base.DefaultFailureHandler$AssertionFailedWithCauseError: 'with text: is "21"'
    </failure>
</testcase>
<testcase name="testButtonClickMultiply" classname="net.yasik.sampleuitest.ExampleInstrumentedTest" time="2.38" >
</testcase>

Double Test Failure:

<testcase name="testButtonClickAdd" classname="net.yasik.sampleuitest.ExampleInstrumentedTest" time="1.438" />
<testcase name="testButtonClickSubtract" classname="net.yasik.sampleuitest.ExampleInstrumentedTest" time="2.06" >
    <failure>androidx.test.espresso.base.DefaultFailureHandler$AssertionFailedWithCauseError: 'with text: is "21"' 
    </failure>
</testcase>
<testcase name="testButtonClickMultiply" classname="net.yasik.sampleuitest.ExampleInstrumentedTest" time="2.06" >
    <failure>androidx.test.espresso.base.DefaultFailureHandler$AssertionFailedWithCauseError: 'with text: is "21"'
    </failure>
</testcase>

Yaml File (Wokflow)

    - name: Publish Test Report with Insights
      uses: ctrf-io/github-test-reporter@v1
      with:
        report-path: 'sample.json'
        summary-delta-report: true
        insights-report: true
        flaky-report: true

        upload-artifact: true

      if: always()

Can u please provide the Workflow to report Flaky Test and also please provide the sample xml

Start by reproducing the reported workflow using ctrf-io/github-test-reporter@v1, the sample.json path, and the attached single- and double-failure XML examples. Check whether the generated flaky report identifies a test present in both results, and consider the issue done when a documented workflow and sample XML produce the expected flaky-test report.
