How to use @sentry/tracing in Node.js?

Documentation for @sentry/tracing with Node.js is not clear.

Do I just have to install @sentry/tracing and import it?

import * as Sentry from "@sentry/node";
import * as Tracing from "@sentry/tracing"; // <--  Tracing is decleared but its value is never read

  dsn: "",

  // We recommend adjusting this value in production, or using tracesSampler
  // for finer control
  tracesSampleRate: 1.0,

I’m using Fastify and TypeScript by the way.
Could you please guide me a little bit?
