oauth 2 parameters can only have a single value: scope

I'm trying as a practical exercise connect Zoho apps with Google API, in this case I'm trying to connect with Google Sheets API. I'm connecting with OAuth2.0 Auth but when I connect the applications throw me this error:

enter image description here

and I was searching why the scope were duplicated but I don't find an answer, the Auth URL would be something like that:

https://accounts.google.com/o/oauth2/auth?client_id=687208587690-aic82a1471cdp97m7s4j4bc15vfms00b.apps.googleusercontent.com&redirect_uri=https://accounts.zoho.com/oauth/v2/auth&response_type=code&scope=https://www.googleapis.com/auth/spreadsheets&access_type=offline&include_granted_scopes=true

scope=https://www.googleapis.com/auth/spreadsheets

I don't know if I configured wrong OAuth consent screen or configured wrong the params in Postman.

Update: I will add more details

I'm trying to connect zoho expense with google sheets via API

In Zoho Expense I can connect with diferents custom services with this: enter image description here enter image description here

The ID client and secret client take them from the credentials of google cloud and with POSTMAN I generated the Auth URL with these parameters:

The URL access token: enter image description here

The URL refresh token: enter image description here

Well, I found a solution, hope this can help another one:

The problem was not the scope, the problem was the parameter:

I change querystring by header:

Auth URL: https://accounts.google.com/o/oauth2/auth?access_type=offline

Access token: https://oauth2.googleapis.com/token

Refresh token: https://oauth2.googleapis.com/token

scope: https://www.googleapis.com/auth/spreadsheets
