ujust get-lsfg-vk execution permission issue

Hello, I tried installing lsfg-vk via teh ujust command, it installs just fine but gives the message "'lsfg-vk-ui' was found in usr/local/bin/lsfg-vk-ui but execution permissions are missing."

I tried going to properties on the file, but all the permission options are greyed out. Uninstalling/reinstalling using the ujust command doesnt work either.
