Okta SAML as IDP setup error

I was checking the Configuration Okta as SAML IDP documentation and it seems outdated.

In my dashboard the “Dashboard → Authorization” does not exist but I’m guessing this is “Dashboard → Authentication” instead. I don’t see any “Save” button instead a “Create” button. Also, the instruction says 3 fields are required but I keep getting an error that is not very helpful

" Error! Something happened while trying to create your connection: Bad Request. Please contact support if the problem persists"

When the error happens it highlights the Sign In URL field where I simply set the value the same as Okta’s SAML “Identity Provider Single Sign-On URL field”.

Any ideas?
