how to override firebase_ui_auth message in multiple languages

Hello,

I am trying to override a few of the error messages in the Auth UI interface, neither want to rewrite all the messages in all the languages nor create my auth interface.

I have followed the doc on extending the FirebaseUILocalizationLabels, but now all non overriden labels are 100% in English.

I have .arb files for the rest of my app, and would be happy to override FirebaseUILocalizations messages from there.

thanks !

I created a simple repo showing the delegate which I want to override. Line 293 in the file below.
