OptionalappData to carry across the round-trip, like signInWith…({ appState }).
OptionalaudienceAudience (Api identifier) for the access token.
OptionalqueryExtra /authorize params merged in as-is. prompt is always none.
Optionalredirectfalse never navigates: when the refresh is refused the call resolves
with an AuthLoginRequiredError instead of starting the prompt=none
round-trip. Defaults to true in a browser.
OptionalredirectWhere the prompt=none round-trip lands (the OAuth redirect_uri).
Defaults to the client's redirectUri, then window.location.origin.
Keep it a clean URL: the user's actual location travels as returnTo.
OptionalreturnWhere the app should put the user back after the round-trip. Comes back
as returnTo in the FaableAuthClient.initialize result — never
in the URL. Defaults to the current window.location.href.
OptionalscopeScope for the token, when different from the client's default.
Options for FaableAuthClient.getTokenSilently.
