Woocommerce products can not be queried in another language

[cankahya]

Describe the bug
It is not possible to query woocommerce products for another locale, using wp-graphql-wpml

To Reproduce
The following query should return the english versions of the products. Instead it returns the main locale (german in this case):
Query
{ products(where: {wpmlLanguage: "en"}) { nodes { id slug name ... on SimpleProduct { id name buecherFields { buchKategorien { nodes { name slug } } } buchInfos { buchInfos } locale { locale id } } } } }

Response

{
"data": {
"products": {
"nodes": [
{
"id": "cHJvZHVjdDoxMDE4Mg==",
"slug": "sollberger-boegli",
"name": "Sollberger Bögli",
"buecherFields": {
"buchKategorien": {
"nodes": [
{
"name": "De aedibus",
"slug": "de-aedibus"
}
]
}
},
"buchInfos": {
"buchInfos": "

},
"locale": {
"locale": "de_DE",
"id": "de_DE"
}
},
....

Expected behavior
The products should be returned in english.

Not sure if this is a bug with wp-graphql-wpml or wp-graphql-woocommerce. Clarifcation would be great!

This is a very crucial feature, which makes the use of graphql for multilangual woocommerce sites impossible.
Please priotize. Also happy Thanks for any tip!

@cankahya I think it might be an issue with wp-graphql-wpml as wp-graphql-woocommerce doesn't interact with translations. Have you tried to contact wpml?

I've also noticed that you are using this version https://github.com/rburgst/wp-graphql-wpml, which seems to be unmaintained.

Have you tried with the official one from here https://wpml.org/documentation/related-projects/wpml-graphql/?

Their version is from 2023 https://wpml.org/compatibility/2023/05/wpml-graphql-build-headless-multilingual-wordpress-sites/

@creative-andrew Thanks for taking your time looking into this. I will test the plugin you suggested and report my findings :)
