Chrome extension with trading API

I have a specific request for a chrome extension (cryptocurrency trading) :

- Attached chrome extension (zip) take information from tradingview.com and send buy/sell order to bybit API.
- I need you to replace the current API with another broker API (Oanda broker) in background.js

Endpoints :
- Trade : https://developer.oanda.com/rest-live-v20/trade-ep/
- Order : https://developer.oanda.com/rest-live-v20/order-ep/

Authentification details in chat

Note :
1) You DON'T need to create a tradingview account to test it
2) Test will be made from a practice account (https://developer.oanda.com/rest-live-v20/development-guide/)
3) That's a small project. Most the job is already done. You just need to change the API
