if I am in the AzureAD portal and go to Enterprise Applications, click "New Application" and then choose Application not found in Gallery.

When you do that, their are 3 SSO options for the new Applications, None of them are OpenID Connect

This is how 99% of all SaaS Vendors instruct people to add new Applications

You need to add an App Registration. The docs are pretty woeful!
