Generate Signature for Promotional Offers: Where is start-server file?

I'm looking at the sample code available here: Generating a Promotional Offer Signature on the Server

Step 4 of "Configure the Sample Code Project" says:

The start-server file contains a key ID and private key PEM string. The values provided in the sample are for example purposes only and will not generate signatures that are valid for your apps. You can optionally open start-server with a text editor and replace the example key ID and private key PEM string with your own key ID and private key PEM string that you received from App Store Connect.

Where is the start-server file? Or can someone share an example of it? It's not in the sample code .zip (as far as I can tell)

I already ran npm install

Thank you for reaching out. I would recommend using the App Store Server Library (Node link) https://github.com/apple/app-store-server-library-node#promotional-offer-signature-creation, as this contains the code already and examples.
