Implementing admin users across multiple organizations

I’m scoping out a migration from devise to Auth0 but want to have a clear plan to achieve relative parity with out current user hierarchy. This is a SaaS provider that works with multiple businesses that will each have their own set of rules (ie. text-based MFA vs app-based vs no MFA). This seems like a perfect case for Organizations in Auth0, but please correct me if I’m mistaken here.

The questions is: as a SaaS provider there are user accounts associated with us, like customer success and developer accounts, that need to have admin access to all Organizations. It doesn’t seem like a reasonable approach to add them to each org, plus users can only be logged in to one org at a time, so that sounds like a non-starter.

Is there a way I can implement this? I was thinking via hierarchical Organizations, but I’m seeing mixed messages in the documentation/community about implementing that
