Hi. I have been trying to send request to obtain access token to send data into the CRM. However, I'm unable to get the access token due to CORS & Bad Request problem. I'm not well versed in sending request to Microsoft via fetch method. I have attached the images below that shows my snippet code and the error I'm getting.

The live site is deployed on Netlify server.

I tried enabling CORS on my browser and solved the CORS issue but the Bad Request was still there.

This works fine on Postman but not in my code.
