Alternative for Thread.Sleep() in a "For Loop" in Kotlin?

I have a for loop that consists of looping towards infinity and inside that for loop, there is a Thread.sleep(T)function, the sleeping time varies from 50ms to 1s. I know there are performance and user experience costs for using a sleep function inside a loop.

So what are the Kotlin alternatives ? (I found answers but all of them are in Java, I wanna know the best alternatives in Kotlin)

Use Kotlin Coroutines there is delay(millis:Long) function that is cheaper than Thread.sleep()

    import kotlinx.coroutines.*


    fun main() {
    GlobalScope.launch { // launch a new coroutine in background and continue
        delay(1000L) // non-blocking delay for 1 second (default time unit is ms)
        println("World!") // print after delay
    }
    println("Hello,") // main thread continues while coroutine is delayed
    Thread.sleep(2000L) // block main thread for 2 seconds to keep JVM alive
}
