Google Conversation Action and Account Linking Language

Question

I've been trying for a while to have my conversational action submitted into three different languages: EN, ES and PT. The action gets approved on EN but not on ES nor PT.

Google tells me that the reason it is not getting approved is because my Account Linking Login page is not translated into PT nor ES. However, that login page is not under my control since my service runs on AWS and I use Cognito's login page to serve as authentication (and Cognito doesn't allow that page to be translated).

Do you have any ideas or reccomendations on how to circumvent this?

Any help is much appreciated.

Thanks
