Hi guys, what is the best way to return a List<String> from a coroutine? My current code is this one but its kinda slow and affects my UI in android

fun fetchUsers(): List<String> {
    val heartbeatApi = HeartbeatApi()
    val users = runBlocking {
        withContext(Dispatchers.Default) {heartbeatApi.fetchUsers() }
    }
    return users
}

You should not uses Default and runBlocking.

What can you suggest? I needed something that has the capability of returning a List<String
