Auth0.Core.Exceptions.ApiException: Insufficient scope, expected any of: create:connections

Hello Community,

I am trying to import bunch of users into Auth0 but I can not create the connection.

I am receiving the message :
Auth0.Core.Exceptions.ApiException: Insufficient scope, expected any of: create:connections
I have tried several approaches, however I have no luck so far.
I checked the token and it is true that I did not have that scope before, so I added it to the API and now it actually have it but still the message is the same.

It happens every time I try to create the connection.

Please, any help will be welcome.

Regards
