Lenovo Ideapad 5 F keys not working

Hello, all. I am new to the Linux environment and was able to setup Manjaro KDE Plasma on my Lenovo Ideapad 5. I almost have everything running smoothly except the F keys not working. I made a temporary custom keyboard shortcut to adjust the brightness but was wondering if anybody knows how to configure the true F keys. As of now, F4, 5, 8,9, Print screen, and Insert are not working. I appreciate it.
