Can't use my OpenAI API keys in my React Native Expo app?

import { Configuration, OpenAIApi } from "openai";
import { OPENAI_API_KEY } from "/.env";

const configuration = new Configuration({
  apiKey: OPENAI_API_KEY,
});

const openai = new OpenAIApi(configuration);

import { Configuration, OpenAIApi } from "openai";
import { OPENAI_API_KEY } from "/.env";

const configuration = new Configuration({
  apiKey: OPENAI_API_KEY,
});

const openai = new OpenAIApi(configuration);
