Capella create channel with OIDC user creation

I have Capella Server set up to use OIDC for user auth, and have configured it in the web UI to automatically create sync gateway users with new valid OIDC credentials. However, I would also like to automatically create a channel for all new users as well, to keep user data separate.

I found this discussion, but it doesn’t seem to apply to Capella Server:

How can I enable this feature in Capella Server?
