I want a mobile app that has a screen with a Google SignIn Button.

I want the code and functional app created on React + Expo that has a screen that has a Google SignIn button. When the app is ran, it must show a screen with a Google SignIn Button, when I click on it, it has to show the list of available accounts on the mobile phone in case there are and then when user enter google creds or select the desired google account it must log in and show the email and the username.
My budget is for the whole project, not per hour.
