Where can I find the Instance Id for my OFS environment?

**This post was created as part of a How to Service Request (SR)

Release: 23.2.1

Summary of the question:

While trying to configure an integration between another Oracle product and OFS, in the docs I found that I needed something called the "instance Id":

"The instance ID is provided by Oracle when your Oracle Field Service Cloud instance is provisioned."

Where can I find that instance Id?
