WhatsApp does not have an in-built feature to allow users to read deleted messages on the platform. The messaging platform introduced the ability to delete messages in 2017, barring its visibility to the recipient. If you have to read deleted messages on WhatsApp, you may have to download third-party applications, including WhatisRemoved+, Notisave and WAMR.

These apps are available for download on Google Play Store and not on App Store.
