Orao Oracle: fail to import JS SDK

Question

When loading the node module @orao-network/solana-vrf to interact with the Orao oracle, I receive this error:

Uncaught ReferenceError: Buffer is not defined at ./node_modules/@orao-network/solana-vrf/dist/index.js

I'm just loading the Orao library in my JS file with:

import {
    Orao,
    networkStateAccountAddress,
    randomnessAccountAddress,
    FulfillBuilder,
    InitBuilder,
} from "@orao-network/solana-vrf";

Orao resources:
