Server internationalization

[plcardonab]

Hello, I have a project using type-graphql and I need to handle different languages like Spanish and English for example I want to execute a query and I want to receive de response depending on the language I specify whether in the header of the request or any other approach. I have tried the following documentation here with not success.
in the image below if I specify "en-US" I should receive the message in English if I don specify I should receive it in Spanish
.

I appreciate any help possible. Thank you very much
