Quick question about restricting permissions for Integrations. I've set up an integration record with just Client Credentials (Machine To Machine) Grant. In the OAuth 2.0 Client Credentials (M2M) Setup I only seem to be able to select users with administrator roles. What permissions are required to make a role appear in the dropdown when selecting a user? I haven't found this in the NS help. I've added these so far:

Setup:
OAuth 2.0 Authorized Applications Management
REST Web Services

Reports:
SuiteAnalytics Workbook

Enabling the Web Services Only Role checkbox didn't make a difference either. Edit: I've got the answer now and it was Setup > Log in using OAuth 2.0 Access Tokens.
