Getting 401 Unauthorized error on google API

I am learning how to use Google Drive API to upload a file and I am getting this error:

"Client error: `POST https://www.googleapis.com/oauth2/v4/token` resulted in a `401 Unauthorized` response:\n{\n \"error\": \"unauthorized_client\",\n \"error_description\": \"Client is unauthorized to retrieve access tokens using this me (truncated...)\n"

I think this stem from a wrong configuration of my service account. When I created my service account, I didn't use Enable G Suite Domain-wide Delegation and just used the generated json key.

Attached here is a screenshot of my IAM & ADMIN enter image description here

I also enabled API for google drive, so what am I missing?

You have to create a client id for the service account and with that id you have to enable the SCOPE in security - advanced configuration
