Adding users to audience

hooks.server.ts (Auth.js boilerplate)
export const handle = sequence(
	SvelteKitAuth({
		// ...
		events: {
			createUser: async (message) => {
				await loops.createContact(message.user.email ?? '', { userId: message.user.id });
			}
		},
		// ...
	}),
	// ...
) satisfies Handle;
