What does it mean when the WhatsApp symbol flashes briefly? (Huawei p30)

Earlier it was so that the WhatsApp sign flashed for 1-2 seconds, then it was gone again. WhatsApp didn't show a new message either.

Does anyone know? A message that has not yet arrived? Interference? Or does it mean nothing at all?
