Supabase Realtime in long-running Node.js — is manual channel re-subscription required?

const supabase = createSupabaseClient<Database>(config.url, config.secretKey);

supabase.realtime
  .channel(`sync-activities-${uuidv4()}`)
  .on("postgres_changes", { event: "*", schema: "public", table: "activities" },
    async (payload) => { /* send push */ }
  )
  .subscribe();

const subscribe = () => {
  const channel = supabase.realtime
    .channel(`sync-activities-${uuidv4()}`)
    .on("postgres_changes", { event: "*", schema: "public", table: "activities" },
      async (payload) => { /* process */ }
    )
    .subscribe(async (status, err) => {
      if (status === "SUBSCRIBED") return;
      if (["CLOSED", "CHANNEL_ERROR", "TIMED_OUT"].includes(status)) {
        await supabase.removeChannel(channel);
        subscribe();
      }
    });
};
subscribe();
