setTimeout in Lens Studio

I’m trying to bring in some web libs, but the setTimeout function doesn’t exist in LS for some reason. I wrote this polyfill, but I’m not sure if it’s kosher. Do I need to clean up the event that I created? Seems like it could eat up memory over time if it’s not disposed.

function setTimeout(f, d){
    var e = script.createEvent('DelayedCallbackEvent')
        // TODO unbind??
        e.enabled = false
