Issues finding other locations in the file manager of Kali 2020 Forensics mode

I am having trying to follow a homework problem for a digital forensics class. The goal is to be able to boot Kali Linux from a flashdrive in forensics mode and then mount your computer’s harddrive as read-only so that you can view and interact with it. I am struggling to confirm my harddrive’s location and the “other locations” tab in the file manager is not showing up.

For your reference here is a link to the problem I am working through (pages 4 & 5)

Any suggestions or work arounds?
