Go to URL at end of stage without CLICK

I'm done building my new intro (HTML5 canvas) for my website in Animate CC 2017.
At a certain frame, the intro is finished and 2 buttons are appearing to chose the desired language.

I could do that with OnClickGoToUrl (or something similar) however, when the user clicks on a language-button, the elements of the intro will fade out first one by one (already did that) and then go to that URL, so without clicking at the end of the scene.

I managed to stop the intro when the 2 buttons are visable first and then On click go to frame # where the fade out begins.

After that, the user should be redirected to the URL (so without clicking bcos he already clicked the button to start the fade out)

But how do I do that??
