WS Federation Template not showing up in dev account

I’m trying to set up a test application for WS-Federation by following these directions, but I’m not seeing a ‘search bar’, nor the “Template WS-Fed” option. I think I’m in the wrong place, can you confirm and direct me, please?

Thank you!

These are the directions I’m attempting to follow:

Note: when I follow these directions, I end up with a 404

A snippet directs me to this page (404) - https://support.okta.com/help/s/article/29510977-Configuring-the-Okta-Template-WS-Federation-Application

I’ll answer my own question in case someone else needs it… It turns out, you have to choose “Classic UI” instead of Developer console here: okta
