Edge Downloads popup window - how to automate it

Hi, I’m working on the process which downloads reports from Power BI. Since bot has to first create report, I’m not able to use ‘Download’ keyword from RPA.HTTP library as I don’t have exact url for it.
I need to inspect the Downloads popup window in the Edge so bot can choose ‘Save as’ option and set a filepath for report. I might be wrong but I haven’t found any existing keyword in Selenium library which could help to automate this step and since this popup is not a part of webpage but browser I can’t inspect it with dev tools. Did anyone try to automate similar action? I haven’t found any guides on the internet so feel a bit helpless at the moment.

Hi, I believe that this popup would need RPA.Windows library to interact. Or maybe it can be disabled by options.
