FB Instant Game - How do I switch to specific ContextID when i click on a button?

I am trying to figure out how can i switch to a specific ContextID when the user clicks on a button. For example I have a list of already started games and when the user clicks on the specific game I want to continue playing that game. In Facebook Documentation I can see that you can call the following which will switch the user to the specified context_id:

FBInstant.context.switchAsync(context_id)

.then(function() {

// We have switched into a previously created context

}).catch(function(error) {

// Some error occurred

});

I don't know how to do this with Construct 3.

Thanks,
