[FLOW] collect the latest emitted value after some time from the latest emission

I’m not sure how to explain my usecase. I have a textfield that emits on each text change but I need to collect the latest value only when there aren’t other emissions for 300ms

flow {
    emit(1) // this won't be collected because 2' is emitted after 40ms '
    delay(40)
    emit(2) // this won't be collected because '3' is emitted after 40ms 
    delay(40)
    emit(3) // this will be collected because it's the latest emitted value
}.specialOperatorWithoutAName(timeInMillis = 300)

// I only want `3` after 380 milliseconds 

I hope someone can help me

In fact, I miss something like a sample but with the last value emitted
