Install Citrix Workspace app 2012 on Fedora 33

Download the RedHat Web Package from Citrix Workspace app 2012 for Linux

Install package

# dnf localinstall Downloads/ICAClientWeb-rhel-20.12.0.12-0.x86_64.rpm

If you updated from a older version i.e. 2004, just remove the changes in desktop file

revert changes from older versions

# sed -i '/Exec=/d' /usr/share/applications/wfica.desktop
# echo 'Exec=/opt/Citrix/ICAClient/wfica -icaroot /opt/Citrix/ICAClient %f' | tee --append /usr/share/applications/wfica.desktop

and you're done, linking certificates is also not necessary with version 2012.
