OptionalcookieAccessPromptStyle?: Partial<CSSStyleDeclaration>OptionalcookieAccessPromptText?: stringOptionalloginFrame?: HTMLIFrameElementOptionalloginHint?: stringOptionalsignal?: AbortSignalOptionaltimeoutMs?: numberOptional upper bound, in milliseconds, on how long the embedded login may take before it rejects
with a TwinfinitySessionError carrying cause: 'timeout'. A silent (hidden) iframe
login defaults to DEFAULT_SILENT_LOGIN_TIMEOUT_MS because a hidden iframe can't be
detected as closed and would otherwise hang forever if the provider never responds. A visible
iframe (the cookie-access consent prompt) is not timed out by default, since the user drives it —
pass an explicit value to bound it.
An optional AbortSignal the caller can use to cancel an in-progress login. Aborting tears down the login iframe and rejects establishEmbedded with a TwinfinitySessionError carrying
cause: 'cancelled'. A signal that is already aborted when login starts rejects immediately. Has no effect once the login has settled. See PopupWindowOptions.signal.
