CORS Policy Issue in React Native

I'm currently encountering a CORS policy error while trying to interact with an API in my React Native application. Unfortunately, I don't have access to the server to make adjustments. I've attempted to resolve this issue by using a proxy server, but I still need assistance.

Details:
- The API request I'm making is a POST request.
- The data being sent in the POST request is in JSON format.

Ideal Skills and Experience:
- Proficient in React Native and JavaScript.
- Strong understanding of CORS policy and its bypass methods.
- Experience in handling API requests and troubleshooting related issues.
- Familiarity with using proxy servers for API requests.
