So it looks like login_hint seems to be passed through. However the documentation states that it "only affects the classic Lock experience. " → but is it oK to be used for this situation?
login_hint: string
Inherited from BaseLoginOptions.login_hint
* Defined in [src/global.ts:41](https://github.com/auth0/auth0-spa-js/blob/3a92890/src/global.ts#L41)
The user's email address or other identifier. When your app knows which user is trying to authenticate, you can provide this parameter to pre-fill the email box or select the right session for sign-in.
This currently only affects the classic Lock experience.
