Permission error when trying to access portal


Hi Team,

I have a hubspot dev account and my dashboard looks as below:

When I try to connect to (2nd portal in above screenshot) through OAuth2, I am getting an error saying "Uh oh!

You do not have the correct role to grant these permissions. Please contact your administrator."

But when I manually go to laban-dev portal and in the users page, I provide “Sales administrator” privilege to my user (my user is venu bandaru as in below screenshot) and then try to connect to laban-dev portal, It works just fine.

Now my query is that, earlier using OAuth1 I never had to provide the Sales Administrator privilege and the connection used to work fine. Is it mandatory that in OAuth2.0, we need to give Sales Admin privilege? I am only trying to access the “Contacts” scope
