Org Plugin – Why client headers needed?

const metadata = { someKey: "someValue" };

const data = await auth.api.createOrganization({
    body: {
        name: "My Organization", // required
        slug: "my-org", // required
        logo: "https://example.com/logo.png",
        metadata,
        userId: "some_user_id", // server-only
        keepCurrentActiveOrganization: false,
    },
    // This endpoint requires session cookies.
    headers: await headers(),
});
