private suspend fun `show progress animation`() {    val progressBarLength = 30    var currentPosition = 0    while (true) {        print("\r")        val progressbar = (0 until progressBarLength)                .map { if (it == currentPosition) " " else "░" }                .joinToString("")        print(progressbar)        delay(50)        if (currentPosition == progressBarLength) {            currentPosition = 0        }        currentPosition++    }}

2. Launch the `show progress animation`() function inside a new coroutine:

runBlocking {    val job = launch { `show progress animation`() }}

3. Delay the parent thread by five seconds:

runBlocking {    val job = launch { `show progress animation`() }    delay(5000)}
