PlayCanvas apps on a website

I’ve got an issue with publishing my PlayCanvas apps on a website. These website will contain ui elements to control the PlayCanvas apps.

I want to publish the PC app (canvas) in a specific div. How to do that?
My website must contain muliple (two) PlayCanvas application (yes, this is necessary). Like for the first one, there is a div container where it should be loaded.
I need access to both application to fire events to them like in the example below or in any other way:

btn_doSomething.addEventListener('click', function() {"DoSomething", "Value");"DoSomethingElse", "Value");

Could you use iframes instead and send messages to the frame?
