What I'm trying to achieve is declarative setup with SSO, so ideally the users of SelfHostBlocks should be able to just declaratively config the service and SSO works out of the box with the correct roleClaim etc. One minor snag is that Immich seems to require onboarding and the creation of an admin user on first launch, so the question is whether there is a way to avoid that? Can I config an admin user from the config.json, or otherwise avoid the creation of the initial admin user? Or perhaps it can be done with the API?
