How to avoid returning to login page after logging in?

[MattHeslington]

Hello Gladly,
I hope you're all well.
I'm trying to stop the user seeing the login page again when they log in successfully by checking on the server whether they are indeed logged in and redirecting them accordingly. On my login page:

import { withAuthUser, withAuthUserTokenSSR, AuthAction } from 'next-firebase-auth'
...
<button onClick={signInWithGithub}>GitHub</button>
<button onClick={signInWithGoogle}>Google</button>
<button onClick={signInWithEmail}>Email</button>
 etc...
 ...
export const getServerSideProps = withAuthUserTokenSSR({
    whenAuthed: AuthAction.REDIRECT_TO_APP,
})()

export default withAuthUser({
    whenAuthed: AuthAction.REDIRECT_TO_APP,
})(Signin)

However, the user sees the login page for around three seconds before being redirected. Am I doing this correctly or is there something wrong with my my getServerSideProps?

Any help very much appreciated!
Cheers,
Matt

Ah, a quick perusal of the docs has set me straight 🤦‍♂️ :

export default withAuthUser({
    whenUnauthedBeforeInit: AuthAction.SHOW_LOADER,
    whenAuthed: AuthAction.REDIRECT_TO_APP,
    LoaderComponent: Loader,
})(Signin)
