error 403 Request had insufficient authentication scopes in postman - postman

Question

I'm trying to retrieve from Postman the answers of a form I created on google form but I can't do it.
First of all I created a form on google form.
I sent it to a person to get some answers.
I followed this tutorial which allowed me to set up oauth 2.0 on postman https://www.vulongtran.com/how-to-use-postman-with-google-cloud-platform-apis
Then as indicated in the api documentation of google form, I put in postman the GET method and I pass him the following url:
I replace obviously the formId by the id of my form which is the following 1FAIpQLSdNlmrvlMXvUlhSjiTb7YsqjHCTYZNRlJlGJnwkxyzNNSPe3A
This gives me the following url:
This gives me the following url:
https://forms.googleapis.com/v1/forms/1FAIpQLSdNlmrvlMXvUlhSjiTb7YsqjHCTYZNRlJlGJnwkxyzNNSPe3A/response
Before sending the request from postman I go on Postman->Authorization and I select the token set up thanks to the tutorial of this site:
https://www.vulongtran.com/how-to-use-postman-with-google-cloud-platform-apis
This does not work I get the following error:
{
"error": {
"code": 403,
"message": "Request had insufficient authentication scopes.",
"status": "PERMISSION_DENIED",
"details": [
{
"#type": "type.googleapis.com/google.rpc.ErrorInfo",
"reason": "ACCESS_TOKEN_SCOPE_INSUFFICIENT",
"domain": "googleapis.com",
"metadata": {
"service": "forms.googleapis.com",
"method": "google.apps.forms.v1.FormsService.GetForm"
}
}
]
}
}
I am completely blocked if anyone can help me please?
