localization - Implementing localized 404 page with Firebase hosting

Question

Say my web app has two locales: English(myapp.com/en/) and French(myapp.com/fr/). I want to localize my 404 pages, so that request to myapp.com/en/non-existent or myapp.com/non-existent would return an English version of the 404 page and request to myapp.comm/fr/non-existent would return a French one.

However, it seems like Firebase Hosting does not provide such functionality by default, as it only allows a single 404 page(source)

So, is there a way of implementing a localized 404 page with Firebase Hosting?
