postman setup issue

Hi Friends,

I follow the guide

https://www.zoho.com/writer/help/api/v1/postman-collection.html

I can create a token well, but I get error when I click "send" button

{
    "code": "OAUTH_SCOPE_MISMATCH",
    "details": {},
    "message": "invalid oauth scope to access this URL",
    "status": "error"
}

my test url is "https://www.zohoapis.com/crm/v3/users", I use "get"

Please help me, let me know how to fix this.

Thanks
