You can find more information about this time in the official documentation

There are currently two ways to use this package, the first of which is with the data persistence of the API built Bako Safe and used in the dApp Bako Safe and there is another without the data persistence, only to generate and validate transactions.

In a simple way, we can implement use without data persistence

import { BN, Provider, Wallet, bn, Address } from 'fuels';
import {
    Vault,
    IPayloadVault,
    IPayloadTransfer,
    sign,
    defaultConfigurable,
    mocks,
    accounts,
    IFormatTransfer,
    NativeAssetId
} from 'bakosafe'

// if you run a local node of FuelVm use http://localhost:4000/graphql
const fuelProvider = new Provider('https://beta-5.fuel.network/graphql');

//
const signers = [Address.fromRandom().toString(), Address.fromRandom().toString()];

// make your vault
const VaultPayload: IPayloadVault = {
    configurable: {
        SIGNATURES_COUNT: 1, // required signatures
        SIGNERS: signers, // witnesses account
        network: fuelProvider.url // your network connected wallet
        chainId: await fuelProvider.getChainId() // get chain id or try 0 to fuel node
    },
    provider: fuelProvider,
};

const vault = await Vault.create(VaultPayload);

// This data is an array with all outputs, we send to 2 diferent accounts
const transfer: IFormatTransfer[] =
    {
        name: `tx_example`
        assets: [
            {
                amount: bn(1_000).format(), // value to send on string formatt
                assetId: NativeAssetId, // to send ETH coins
                to: Address.fromRandom().toString() // destination of coins
            },
            {
                amount: bn(1_000).format(), // value to send on string formatt
                assetId: NativeAssetId, // to send ETH coins
                to: Address.fromRandom().toString() // destination of coins
            }
        ]
    }


// Create a transaction
const tx = await vault.BSAFEIncludeTransaction(transfer);

// use the fuel wallet to collect signatures
tx.witnesses = [
    //your signatures
]

// Send transaction
tx.send()
const result = await tx.wait();

If you need use the version with data persistence, check this tests to verify implementation.
