How can I calculate exact duration for test run in Azure DevOps? I do not want to have test run pause time in duration

Question

I want to calculate the test run duration. I see the start time and duration in Azure DevOps but it is included also the pause time. test run was 5 minutes and rest was pause time but it shows the duration 16 minutes!

enter image description here

I tried REST API call but I got the same result! I expect to have approximate time estimation for each test run.
