How can I add Grok 3-4 and any related models?

[AumCoin]

I updated Librechat but I don't see Grok in the .env file or the UI. I created librechat.yaml and added my API key as described at https://www.librechat.ai/docs/configuration/librechat_yaml/ai_endpoints/xai, then added the list of model names on https://docs.x.ai/docs/models. Then I added my API key to .env, but when I brought up the container I still don't have xAI.

Can anyone tell me how to add xAI?

If on hugging face, maybe you can add a variable for xai/grok and add the models to those (look at the other variables for an example).
