Which redirect URI should I use when creating a QuickBooks flow on AppFlow?

Hello

I need to create a flow in AppFlow using the Quickbooks connector. After I enter the ID, Secret, URL and CompanyId I get the following error (for now I'm using the sandbox enviroment, not production):

"The redirect_uri query parameter value is invalid. Make sure it is listed in the Redirect URIs section on your app's keys tab and matches it exactly. Click here to learn more about the redirect_uri query parameter."

After looking up in the QuickBooks Documentation, looks like I need to set a special URI that belongs to the connector (Postman in their example), but I don't know which one should I use with Amazon AppFlow. This Redirect URI is entered in the Settings of the QuicbkBooks app (not in AWS of course).

I tried adding the following ones in the QuickBooks Redirect URI settings, but the same error appears: "https://us-east-1.console.aws.amazon.com/appflow/oauth" "https://developer.intuit.com/v2/OAuth2Playground/RedirectUrl" "http://localhost" "https://sandbox-quickbooks.api.intuit.com/v2/OAuth2Playground/RedirectUrl"
