This page made it trivial to do:

You just need to provide the tokens and access information.

There is nothing simple about this.  You need to create an app and there is no explanaton about how to create the App.

To be specific about ReginaB41's steps on how to get the ID without having to build some kind of utility, here are some details.  I use Firefox's Developer Tools (F12).

1. Go to your Contacts tab in your CC account,
2. Press F12 to pull up the developers tools.
3. Click the Network tab at the top (probably the last tab)
4. Go back to your CC account page and click "Email Lists" from the left sidebar
5. Back in Developer Tools, you will see the list of "Files" update and one of the items in there will end in "/lists"
6. e.g.  /ui/accounts/###############/lists
7. Click that
8. Then on the right, click the "Response" tab near the top of the page.
9. To make is easy, copy all that appears in the window and paste it into a editor. 
10. Do a search on seq_id and you will see a JSON list of your CC lists with all their associated parms.  seq_id is the list ID you need.
11. Profit
