Screencastify Won't Record My Desktop!

There is a known issue with Screencastify and MacOS Catalina not recording the whole desktop. You'll have to allow it to record your desktop.

How do I know if I have Catalina?

First, Click on the Apple Icon on the top left of your desktop and choose "About This Mac"
Menu bar contains the Apple Icon, followed by Finder, file, Edit, View, and Go. The first menu item is About this mac. Then, System Preferences... 1 update. Then, App Store... 1 update. Then, Recent Items. Then, Force Quit Finder with symbols representing the Option, Shift, Command and Power keys. Then, Sleep. Then, Restart... Then, Shut down... Then, Lock Screen with symbols for control, command, and Q. Finally, Log out teacher with symbols for Shift, Command, and Q.

A box will appear. This will tell you your operating system. If it says Mojave on your teacher leased laptop, you're fine. It will look something like this:
Overview, Displays, Storage, Support, Service. macOS Mojave. Version 10.14.6. Mac Book Pro(13-inch, 2019, Four Thunderbolt 3 ports). Processor 2.4 GHz Intel core i5. Memory 16 GB 2133 MHZ LPDDR3.

However, if it says Catalina, like this:
