Last year WhatsApp finally introduced disappearing messages or, as they are called in the application: temporary messages. The option was a bit disappointing for those looking for ephemeral conversations such as Snapchat or secret chats from other applications, because the period in which the messages disappeared was one week.
Apparently more ephemeral features are on the way. On the one hand, the application has been working on photos that can only be viewed once. On the other hand, it will let you choose what messages disappear the next day when activating temporary messages.
