My initial issue was resolved by this solution:
Then after running the final command from the above post, this is the output

Pulse Secure is now listed as a program in my computer. However, when trying to open, there is no response from the program (i.e. there is no GUI that appears.)
What are the next steps for opening Pulse Secure?
Probably of you do a ldd on pulseUi, you will see libwebkitgtk-1.0.so.0 is not installed.
$ ldd /usr/local/pulse/pulseUi
To fix it, you just need to add Bionic Beaver (18.04 LTS) repository (or adapt to PopOS)
# add-apt-repository 'deb http://archive.ubuntu.com/ubuntu bionic main universe'
Then install the missing package.
# apt install -t bionic libwebkitgtk-1.0-0
Tested with Pulse Secure 9.1R4
@B-E_Susan Pulse UI will not be displayed in case of any missing dependency packages, please review @flipPipe's update, and see if that helps.
