How to use the @sentry/node.getCurrentHub function in @sentry/node

const exitProcess = () => {
  const sentryClient = Sentry.getCurrentHub().getClient();
  // eslint-disable-next-line promise/catch-or-return, promise/always-return, promise/no-promise-in-callback, no-process-exit
  if (sentryClient) sentryClient.close(2000).then(() => process.exit(1));
  else process.exit(1); // eslint-disable-line no-process-exit
};

async trackError(err) {
    if (!this.sentryInitialized) {
      return;
    }
    Sentry.captureException(err);
    // Returns a promise that will be resolved in 2000ms,
    // which is the timeout to resolve all pending communication
    // with Sentry servers.
    // @see https://docs.sentry.io/learn/draining
    const client = Sentry.getCurrentHub().getClient();
    return await client.close(2000);
  }

flush() {
    // Give 2 seconds to flush Sentry data
    const sentryClient = Sentry.getCurrentHub().getClient()
    return sentryClient ? sentryClient.close( 2000 ) : Promise.resolve()
  }
}

async function cleanup (exitCode: string) {
    await Sentry.getCurrentHub().getClient()!!.close(2000)
    if (global.discord) await discord.client.destroy()
    console.error(exitCode)
  }
}

export function drain() {
  const client = Sentry.getCurrentHub().getClient();
  if (client) {
    return client.close(2000);
  }
  return Promise.resolve();
}

(params, callback) => {
        spans.compile = Sentry.getCurrentHub().startSpan({
          op: 'compile',
        });
        callback();
      }
    );

export function closeSentry () {
  return Sentry.getCurrentHub().getClient()!!.close(2000)
}
