I couldn't add data from saleforce

[user27]

I try to add data from salesforce,
i have installed AppSheetConnecter on production environment

After pressing the salesforce button, I am redirected and returned to the original page and the following error message is displayed
[Auth failure: this email address has not been verified by Salesforce. Please verify the email address with Salesforce before using it for AppSheet sign in.]

Please tell me what else to do
