Turn on the history in the script editor (topmost 4 checkboxes) - turn it off when you do Art work.
Run the manual command.
Use the MEL-command whatIs to find out what things are

Example: whatIs changeToolIcon
// Result: Mel procedure found in: C:/Program Files/Autodesk/Maya2019/scripts/startup/changeToolIcon.mel // 

It's either a runtime command or a MEL-script. If it's a runtime command then the name is the same in MEL as it is in Python and you can access it like maya.core.theCommand and the flags +command description can be found in the official docs.

If it's a MEL-script native to the application then open it up in a text editor and see what it does. The commands are inside.
