TypeError: Cannot read properties of undefined (reading 'addEventListener')

[codeicey]

I was trying out second usage in liftoff docs and ran into this error:

Steps to reproduce

`
import { createOrbitDB } from "@orbitdb/core";
import { createLibp2p } from "libp2p";
import { createHelia } from "helia";
import { DefaultLibp2pOptions } from "@orbitdb/liftoff";

const libp2p = createLibp2p({ ...DefaultLibp2pOptions });
const ipfs = await createHelia({ libp2p });

const orbitdb = await createOrbitDB({ ipfs });

const db1 = await orbitdb.open("db1");
await db1.add("hello world!");
console.log(await db1.all());
`

Error log

It looks like pubsub isn't available because there is a missing await when calling createLibp2p.

Update the following line and it should work as expected:

const libp2p = await createLibp2p({ ...DefaultLibp2pOptions })

The usage docs have been updated to reflect this fix.
