Hi @Sridhar Renganathan ,
Thanks for reaching out.
To configure any social idP in your Azure AD B2C application, require you to create userflow or custom policy that you want to use for social login.
You can create user flow/custom policy to setup Google IdP as mentioned here https://learn.microsoft.com/en-us/azure/active-directory-b2c/identity-provider-google?pivots=b2c-user-flow
Then you can configure authentication in Node.js by passing user flow/custom policy in the configration file in node sample which automatically allow social idp on signup/sign in page.
Hope this will help.
