iOS RXSwift What is the equivalent of debounce which lets through first event only?

I have a button which sends network requests. I want to ignore double taps within this button. I tried .throttle, but that didn't seem to work. So I'm trying .debounce - this indeed ignores duplicate taps, but only lets through the last event.

What I want is: On first tap, send a network request, ignore subsequent taps within 0.33 seconds.

Which RXSwift operator would help me put an event through and disable subsequent events within a time window?

let buttonPressObservable = button.rx.tap.asObservable()

buttonPressObservable.debounce(0.33, scheduler: MainScheduler.instance)
.map{/*do stuff*/}

In version 4.2 of the library, throttle has a parameter latest that is set to true by default. If you set that to false, I think it will give you the behavior you want.
