Pass value to the embedded app from custom visual
Have you tried window.window.postMessage to send data from ifame into main window?

Tried, but not working. Is there any other solution? Is the sandboxed iframe blocking these events?
As far as I know, Power BI doesn't block such events since it's used for communication between main window and other custom visuals.
Can you share the code for furhter debugging?

Hi,
same problem here.
In the other thread (link), you were saying that PowerBI uses iframe sandbox, maybe that is why postMessage is not working?

Correct. Custom Visuals API loads visuals in an iframe.
Why do you want to use postMessage?
