>End-to-end encrypted services such as Whatsapp or Signal would have to implement the automated searches “prior to transmission” of a message (so-called client-side scanning, Article 10a).

So app developers would be required to add code that will scan every message you send for "sensitive" content (which can be defined however the politicians like and be changed any time), and the app will report your message to the government.
