Ultimately I'm just trying to figure out the paths available to me for provisioning a Custom Web App using Client Credentials Grant in an existing Enterprise account. I understand I need "Admin" approval for that Custom App to do anything but it's unclear to me what my options are for getting it.
1. Can existing Enterprise accounts issue "Developer" accounts.
1a. What's really gained by having a "real" Developer account vs. the free one. Seems like for my use case all it gets me is the ability to hit "request authorization" on my app's configuration page?
2. Can existing Enterprise accounts provision new/existing users with 'Admin' permissions that could then approve of a Web App. If so where are the directions for doing this.
