GraphQL API authentication with JWT tokens in headless Magento

Setting up a React Native app with Magento 2.4.5 backend. Need help implementing secure JWT authentication flow for GraphQL API calls. ## Current Setup - Magento 2.4.5 Open Source - React Native 0.72 - Apollo GraphQL Client - Custom JWT module installed ## Issue Current setup returns 401 unauthorized when trying to access customer data after login: ```graphql mutation { generateCustomerToken(email: "test@example.com", password: "password123") { token } } ``` The token is generated successfully, but subsequent requests fail: ```graphql query { customer { firstname lastname email } } ``` ## Headers Sent ``` Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9... Content-Type: application/json ``` Getting "The current customer isn't authorized" error. What am I missing in the authentication flow?
