The button could read "Improve this text", so it's more clear what it does, perhaps? Otherwise, improve could also mean something like "help improve the assistant", etc.

IMO this should be done with an event (still listen and handle the event here), not by providing a callback to the child components. Wdyt?

It seemed easier to not use events because I would need to pass them through all the components, but I've changed it now to use events.

You could use the Nextcloud event bus so the event does not have to be forwarded by every component.
