Finding my home library on my passport

I bought this external driver to back up my MacAir. I had to reinstall a new system which Apple Store did for me(Big Sur) and they used this passport ultra drive for this.
I needed to look at some info on this drive when it was first backed up. In my user file the library is not there. I am guessing it is hidden. I can unhide hidden files on my mac but cannot figure out how to show my user library on this backup drive.

Can a community member send me a step by step way to unhide my backed up user library? Is it possible the library is not backed up for some (unnecessary) privacy concern?
