[Typesafe HTML DSL] Is there a way to handle keypresses?

I know it sounds quite trivial, but I’m having quite the trouble getting it to work. The only way to do it (that I’ve seen) would be to add a handler on the window or document objects, like:

window.addEventListener("keydown", { e: Event -> console.log(e) }) 

However, the Event object obtained is the most basic event object there is. Most importantly, it doesn’t have a key or code property. There is a type of event handler specifically made for key presses (KeyboardEventHandler<Element>), but I can’t add it on the window or document, as it’s not a React component. Would anyone know anything about this?
