/**

Answer 1

For those using the new interface for Apps Script, normally you would add a service in the editor itself (Files, Libraries, Services):

Unfortunately the AdminDirectory service does not seem to be available in the new interface (as at July 2022). For the next few months while the classic editor is still available, you can click "Use classic editor".

From there it's as Amit explained, Resources menu → Advanced Google services... then turn on AdminDirectory next to Admin SDK API:

Once you've added the service you can go back to the new interface to continue editing and it will show up in the expected spot:

Answer 2

You need to enable the API in 2 places.

1. Inside the Google Script Editor, go to Resources > Advanced Google Services and enable the Admin Directory Service.

2. Next go to Resources > Google Cloud Platform Project > Enable API and Services. Search for Admin SDK and enable the API.
