Place it as the reply beat in a chat-based edit, after the WhatsApp Message Sound sets up the incoming message and before Olha a Mensagem closes the exchange, so the sequence reads as message, reply and reaction.
关于此声音
This is a 17-second WhatsApp audio clip presented as a single soundboard button for quick chat replies. It has the informal, familiar feel of a voice note passed between friends, making it easy to drop into a conversation without a long setup. It works as a short, self-contained reply that listeners can recognise at once from its WhatsApp-audio style.
