Place it after the message lands and before your reply on screen, so the reaction reads as your answer. Pair it first with a WhatsApp message sound for the incoming ping, then follow with a Kiko laugh if friends start teasing you back in the edit.
关于此声音

It feels awkward and endearing at once, like someone quietly admitting embarrassment rather than making a big announcement, which makes the hesitation itself the joke.
