Google Sign-in with register if not already.

[CustomRomHarsh]

i have implemented the clerk with custom UI and my custom sign in component is in the base_url itself.
everything is fine, i ve managed to get it work well.
the one major problem i am facing is :-

when the user clicks google signin button from the base url/sign-in for the first time, it just keeps looping it doesnt create a new account and log it in.

i need to go sign-up manually first then tap on google signin and then if i logout and try logging in from signin/baseurl it loggins.

i just want that if the user is clicking on googlesignin button from the mainpage/signin page it should create the user in clerk if not already then signin. something like signup button

//sign-in page on custom ui google button onClick
await signIn.authenticateWithRedirect({
            strategy: 'oauth_google',
            redirectUrl: '/sso-callback',
            redirectUrlComplete: '/',
            continueSignUp: true,
        });
