How to use the bigchaindb-driver.Connection function in bigchaindb-driver

var BigchainDB = require('bigchaindb-driver')
var bip39 = require('bip39')

// ***************************************************************
// Simple example:
const alice = new BigchainDB.Ed25519Keypair()
const bob = new BigchainDB.Ed25519Keypair()
console.log(alice)
const API_PATH = 'http://127.0.0.1:9984/api/v1/'
const conn = new BigchainDB.Connection(API_PATH, {
     app_id: '',
    app_key: ''
})


// copy to file
const enemy = new BigchainDB.Ed25519Keypair(bip39.mnemonicToSeed('seedPhrase').slice(0, 32))

createAssets()

async function createAssets() {
    const enemyAsset = await createEnemy(enemy)
    // Transfer transaction
    console.log('Enemy created', enemyAsset)
    const groupAsset = await createGroup(enemy)
    console.log('Group asset created', groupAsset)
