I tried to do that and it does seem like PAD has hard time finding the Options and Settings view in Power BI. But when I switched to MSAA -capture mode it seemed to find it.
But even then when I tested the selector it failed to find the element so I needed to simplify it a lot by taking most of the elements off from the selector.
So I only left the last element (number 15 named "Button 'Options'"). Then it worked.
Downside is that making the element so simple it makes it much slower and so the action takes like 15 seconds to find the element.
But I decided to test if I captured any element I could from the Power BI with the default UIA -capturing mode and just rewrote the selector in Text mode to be the
button[Name="Options"]
That actually made it work and much faster (took like 5s to locate the element).
So try to just copy and paste this:
button[Name="Options"]
To your selector and see if that works.
If you will get error about the window element then make sure the window element is not referring to a name that might be different on different flow runs. If you only ever have one Power BI window open then you can just toggle the "Name" attribute off so that it doesn't try to find a window with that exact name.
