How do I use the JavaScript API to manipulate non-authenticated Power BI reports (published to web)?

[ErnstO]

I have several reports that I have successfully embedded and changed inside of a simple test application. I have even made it so that the pages change from two custom buttons I have implemented. However I would like to know if I still have the ability to change pages via external buttons I implement in my application if the reports are published to web? I can only currently manipulate authenticated reports, but how would I go about doing this for outside Power BI report that are public?

Based on my test, it seems not possible. When I try to get a report istance the same way as "manipulate authenticated reports", instead of a valid report instance, I got error "You attempted to get an instance of powerbi component associated with element, but there was no associated instance". 

var reportContainer = $('#reportContainer')[0]; 

report = powerbi.get(reportContainer);

You can try submit your request in that github library.
