currently building my first Google Chrome Extension simply transfer the inputed data from the fields to quickly capture and export to google sheet

Errors I keep getting: 1) OAuth flow did not succeed or no response received. 2) Unchecked runtime.lastError: Could not establish connection. Receiving end does not exist.

Even asking copilot and chatgpt can’t seem to figure this out.

I doubled checked I have the correct IDs as well with no luck here.
