How to Get Wireless Connection in Minimal CentOS 8 for ownCloud

I installed a minimal CentOS 8 directly onto my laptop hard drive with nothing else on it. I then started following this guide but it already assumes that you have a network connection. I then tried this but when when I go to "edit connections", nothing is there. I have a few months experience with different distros for college classes, but it was usually with a GUI and some terminal, and I could usually find the perfect article to walk me through it.

Network Manager service is active(running) and the loopback and wifi device say unmanaged. Please let me know if you can help, I really appreciate it. I have tried googling the answer, but I don't really know which site is correct with what I'm asking because one site says change some configuring files and another says download drivers. :(
