Forward HTTP-Only cookie in server action | Next.js | Page 1

Hey there, upon login my server sends an http-only cookie with a jwt token. I'm trying to handle my login form submission with a server action. I can see the Set-Cookie header in the response, but it's not making it's way to the browser. Is there a way to forward the cookie from response?

"use server";

export async function authenticate(formData: FormData) {
  try {
    const res = await fetch("http://localhost:3000/signin", {
      method: "POST",
      headers: {
        "Content-Type": "application/json",
      },
      body: JSON.stringify({
        email: formData.get("email"),
        password: formData.get("password"),
      }),
      credentials: "include",
    });

    console.log(res.headers);
  } catch (error) {
    console.error("Invalid credentials.", error);
  }
}

The only thing i see I can do is cookies().set() but that requires me to parse the header manually and reset all the settings, I'm not into it.

It works fine if i submit the form client side so I know the api is working good
