@Talcite there's another bit that's potentially keyed by language, where the script reads the message body to determine which site it refers to:

delete-applications/delete-applications.user.js

Lines 119 to 122 in b9ca1a6

	// Which wiki is the application for?
	const wikiMatch = this.previewText.match(
	/applied for membership on (.*), one of your sites/
	)

Are you able to get the localisation strings for this part as well, if any?

EDIT: Actually I just spotted that you added the source in your Discord message, so I can find them myself
