Description

activist adopted the use of the i18nMap object in #1094. One thing that's needed is that the functionality to update the map should be ran each time the frontend is built to make sure that new developers in the community don't run into issues when they update the i18n keys and forget to update the object. Ideally this would be the frontend/i18n/check/i18n_generate_map_object.py script being ran on yarn build, but we can also look into other solutions here :)

Contribution

Happy to help devise a solution to this and work with people to implement this functionality! 😊
