Can't get Bearer Token from `ctx.response.headers.get("set-auth-token")`

export const authClient = createAuthClient({
    fetchOptions: {
        onSuccess: (ctx) => {
            const authToken = ctx.response.headers.get("set-auth-token") // get the token from the response headers
            // Store the token securely (e.g., in localStorage)
            if(authToken){
              localStorage.setItem("bearer_token", authToken);
            }
        }
    }
});
