Google Docs can not work while Google Sheets and Calendar have no problem

[NUSLCC]

I was trying to add a regular Google Docs node and it prevented me from accessing by showing “Unable to sign without access token”.
However, I followed the process to add OAuth 2.0 Client in Google Platform. How can I diagnose where is the issue?
While Google Calendar, Gmail, Google Sheets had no problem since they did not need id & secrets in adding the credentials. All the google api have been enabled in the Google Cloud Platform.

When clicking sign in with Google in adding credentials:

Access blocked: n8n.cloud has not completed the Google verification process
n8n.cloud has not completed the Google verification process. The app is currently being tested, and can only be accessed by developer-approved testers. If you think you should have access, contact the developer.
If you are a developer of n8n.cloud, see error details.
Error 403: access_denied

Details:

Node type:
`n8n-nodes-base.googleDocs`
Node version:
`2 (Latest)`
n8n version:
`1.84.1 (Cloud)`

Thank you @solomon and the video is awesome. It turns out that I need to sign in the google once I fill the ID & secret, it should be a chain behavior. And also I forgot to add myself as test user. Really appreciate the info!
