I set spine interface scale with command line according to the Spine User Guide on [http://esotericsoftware.com/spine-command-line-interface](https://) but an error occurred showing "Invalid UI scale", I don't know where I did wrong.
this is what the command line returns
`Zoc-MacBook-Pro:~ z$ /Applications/Spine.app/Contents/MacOS/Spine --ui-scale 120
Spine Launcher 4.1.12
