Rosaholics Wholesale review for Users Insights & Social Login

Hello good day. I would like to install your app in my shopify store but I have a registration form with certain information that I request from my clients, including their email and password. Is there a way to integrate your app with my form? , and when the user logs in through his app (Social Login) check my customer registry and if his email account already exists, let him log in. The problem is that it does not allow logging in because its app verifies my customer record and since the client's email already exists, it does not allow logging in.
