Detecting clicks on an html viewer

My app displays an html viewer which loads an external web page (that I have no control over) that in turn displays two buttons. I would like to know which button the user clicked. How would I go about that?

sorry for the duplicate, the forum software didn’t show the thread initially.

Hi Maximilian,

next time you get the red error message, access the forum home ( from another Tab / Window and watch if your thread appears or not, so you only have one entry.
