What is the alternative in HarmonyOS for postDelayed() in android?

I am working on an HarmonyOS library that prompts users to review the app on the app gallery. I want to display a prompt thanking the user after he/she reviews the app and the prompt should fade after "int thanksDisplayTimeMs". In Android, it is implemented using

 postDelayed(new Runnable(){
     @Override
     public void run() {
     }
 }, thanksDisplayTimeMs);
