const session = new StringSession(""); // You should put your string session here
const client = new TelegramClient(session, apiId, apiHash, {});

(async function run() {
  await client.connect(); // This assumes you have already authenticated with .start()

  const result = await client.invoke(
    new Api.upload.SaveBigFilePart({
      fileId: BigInt("-4156887774564"),
      filePart: 43,
      fileTotalParts: 43,
      bytes: Buffer.from("arbitrary data here"),
    })
  );
  console.log(result); // prints the result
})();
import { Api, TelegramClient } from "telegram";

const session = new StringSession(""); // You should put your string session here
const client = new TelegramClient(session, apiId, apiHash, {});

(async function run() {
  await client.connect(); // This assumes you have already authenticated with .start()
