Show which key word triggered a notification

Your use case

What would you like to do?

When you subscribe to notifications by key word, you get the whole message highlighted. It would be convenient to highlight the key word that triggered the notification, rather than the whole message.

Why would you like to do it?

Some users have many key words (use case : monitoring news on tech subjects to keep up to date with tech), and want to see easily whether the notified message is actually useful for them or not. When there is a long message, they may read the whole message and then realize it's not interesting.

Example from user report : the key word is "xen", which is mentioned partway through but is not the central subject of the message at all. (in french sorry)

How would you like to achieve it?

Highlight the key word in the message, rather than (or additional to) the whole message.

Have you considered any alternatives?

Additional context

No response

The issue names no implementation files or tests. Start by locating the Element client code responsible for keyword-notification highlighting and trace where the whole message is currently highlighted. Done means the keyword that triggered the notification is highlighted, either instead of or in addition to the whole message.
