Your Code

const venom = require('venom-bot');

venom
  .create({
    session: 'session-name', //name of session
    multidevice: false // for version not multidevice use false.(default: true)
  })
  .then((client) => start(client))
  .catch((erro) => {
    console.log(erro);
  });

function start(client) {
  client.onMessage((message) => {
    if (message.body === 'Hi' && message.isGroupMsg === false) {
      client
        .sendText(message.from, 'Welcome Venom 🕷')
        .then((result) => {
          console.log('Result: ', result); //return object success
        })
        .catch((erro) => {
          console.error('Error when sending: ', erro); //return object error
        });
    }

For multi device beta, the following config created the tokens for me automatically:

const client = await create({
        session: 'wa-session', //name of session
        multidevice: true, // for version not multidevice use false.(default: true)
        folderNameToken: 'tokens', //folder name when saving tokens
        mkdirFolderToken: './data/app', //folder name when saving tokens
        createPathFileToken: true})

Setting folderNameToken, mkdirFolderToken and createPathFileToken were the magic config that created a large session specific token folder that was reused when restarting the server.

For non multi device, you have to save it manually using client.getSessionTokenBrowser() and then read it back and pass it as an option to create as browserSessionToken.

The following works for both multi device and non:

import { create, Whatsapp } from 'venom-bot';
import fs from 'fs';

const TOKEN_DIR = "./data/app/tokens";
const TOKEN_PATH: string = TOKEN_DIR + "/wa-session.data.json";

export default async function createWhatsappClient(): Promise<Whatsapp> {
    var browserSessionToken: any = null;
    if (fs.existsSync(TOKEN_PATH)) {
        const savedTokenString: string = fs.readFileSync(TOKEN_PATH).toString();
        browserSessionToken = JSON.parse(savedTokenString);
    }
    const client = await create({
        session: 'wa-session', //name of session
        multidevice: true, // for version not multidevice use false.(default: true)
        folderNameToken: 'tokens', //folder name when saving tokens
        mkdirFolderToken: './data/app', //folder name when saving tokens
        createPathFileToken: true,
        disableWelcome: true,
        disableSpins: true,
        headless: true,
        browserSessionToken: browserSessionToken,
    });
    const token: any = await client.getSessionTokenBrowser();
    await fs.promises.mkdir(TOKEN_DIR, { recursive: true });
    await fs.promises.writeFile(TOKEN_PATH, JSON.stringify(token));
    return client;
}

you can save the session token manually. See here in this script! The comments are in Portuguese, but you can translate the page. OK!?
