Currently I have a simple dialogflow project for Google Home which uses the Google Sign-in feature to retrieve information from a logged in user. When I start the app, Google Sign-in will ask me if I allow my app to create an account and use my information.
Is it possible to change the above placeholder text or any of the other Google Sign-in dialogs?
Thanks in advance!
No. That is common language that applies to all Actions on Google.
While this is not stated explicitly in the documentation here [1], everything that is actually customizable is covered in project configuration and starting the authentication flow sections.
