Prey + Little Snitch (Catalina) - previous solution not working anymore

Hello, I am on Macos 10.15.3 Catalina and have been a long-time user of Obdev’s Little Snitch. Setting up Prey to work with LS is kind of a challenge with Catalina. The previously functioning solution mentioned on this forum quite apparently does not work anymore. When I input that SUDO command sudo -u prey /Applications/Little\ Snitch\\ Snitch\ Configuration into Terminal the answer I receive is:
sudo: unknown user: prey
sudo: unable to initialize policy plugin

I guess we need a new solution or a slight change to that code: can anybody help?
