I studied the new i18n feature in Angular 9. https://angular.io/guide/i18n
How to translate text in TypeScript, e.g. SnackBar messages?
The better way of translationId is:
title = $localize`:@@Home.Title:Some title text`
and you have to manually add it to your messages.xx.xlf (for example messages.fr.xlf and so on)
Some title text TRANSLATION_HERE
