Solid way to Show components based on information from the session or cookies or server only data?

const updates300 = ["user1", "user2", "user3"];

export default async function Home() {
  const user = await getUserOrRedirect();

  return (
    <div className="flex flex-col items-center justify-center p-4">
      <H1 className="text-center">Welcome {user.fullName}</H1>
    {updates300.includes(user.userId) && <Update300 />}
    ...
    </div>
  )
}
