How to list available VisibleExternalCommands from within JEA session?

hi all,

I’ve set up a JEA endpoint with VisibleExternalCommands pointing to a custom script and it works fine if I launch it by typing the full path.
I struggle to find a way of letting users of this restricted JEA session know which external commands are available.
If I run “get-command -commandtype all” from within a JEA session I only get default functions and aliases, but it does not list my custom script in there.
Any ideas??
