### Describe the Bug with repro steps

Much like we do with API Center, if a customer has chosen to use OAuth Authentication, our Logic Apps hould take care of creating:

- App Registration
- Enabling EasyAuth based upon default configuration that we use with APIC.
- This includes Scopes and Audiences
