SSO & SAML service requirement

I am just trying to figure out whether or not the SSO/SAML App requires the enterprise edition of nextcloud or not.
https://docs.nextcloud.com/server/11/admin_manual/configuration_server/sso_configuration.html

It seems the SSO/SAML App for ownCloud does require enterprise, but as far as I can tell there is nothing which states that I require enterprise nextcloud to use it. So rather than just assume it doesn’t and go through the process of setting up nextcloud on my server, I’d like to get confirmation first that I can use this without the enterprise edition.

Yes, You are right.
You do not require the enterprise edition of nextcloud for SSO/SAML.
I am running one instance with SSO/SAML on my own and it is working well
