How to use this module?

[COArikan]

Dear creators,
I've installed the module, enabled it and executed composer install command in the module folder..
Also added authsources section properly..
But, how can I use it? How can I start users to use it and set their authenticators?
My simplesamlphp version is 1.18.3.. The sources like for the older versions but I converted clas names to namespaces..
Still can't find how to use it..
Could you please explain it?
Thanks..
