I need to know how long did it take a task under one column to another

I connected Asana to Power bi which is great! Now, one of the tasks is to know how long it takes for a task spent in one column before it gets moved to another column in our Asana board. While this feature is available on the Asana dashboard, I need to have it on Power Bi.
I am looking forward to hearing back from you. Thanks much!
