How not to violate the Play Market rules?

Made an application for Yandex Money (Yu.Money). He counts how many receipts were in the wallet. At the first launch, authorization is required to receive a token. Authorization takes place on the Yandex Money website. Google rejected my post with the wording

The main purpose of your application is to provide viewing of the website

I tried to explain in the appeal that this is needed only once and for authorization, but they stand their ground. What to do if authorization through the website is required? Has anyone faced such a situation?
