Where is a pinboard launcher if not in the Desktop folder? [SOLVED]

[JASpup]

The launcher points to a standard /usr/share/applications menu launcher, but the desktop icon itself is not represented in /root/Desktop which is empty.

Where could it be in 32-Xenial?

My goal is to remove it via script instead of the -Remove Item(s) right-click menu option.

It's a line in /root/Choices/ROX-Filer/PuppyPin.

Delete it and restart X works though not sure how to achieve the same result without restart, i.e., the --Remove Item(s) choice.
