Language directive support in graphql schema

What I want to do

I want to control the value of my field based on the language via my graphql schema.

It seems that we can’t use Language Support - Query language since the lang directive is not supported in the graphql schema. Technically the language support is useless now.

Is there any workaround or we are doing something wrong?

What I did

There is nothing I can do
