Open the "solid menu". You find the App at the bottom of the list. 
The usage is self-explanatory. Just change the settings. 

Install:
The installer that ran when you downloaded this app/plug-in from Autodesk App Store will start installing the app/plug-in. Or, simply double-click the downloaded installer to install the app/plugin.

Uninstall:
You can unload the add-in without uninstalling it by clicking the "Stop" button when the add-in is selected in the list box on the "Add-Ins" tab of the "Scripts and Add-Ins" dialog.
Unchecking "Run on Startup" causes the add-in not to be loaded in future sessions of Fusion 360.
To uninstall this plug-in, exit the Autodesk product if you are currently running it, simply rerun the installer, and select the "Uninstall" button.

Or, you can uninstall it from 'Control Panel/Programs and Features' (Windows 7/8.1/10), just as you would uninstall any other application from your system. 

Scripts and AddIns lead to crash in Fusion360 when the user turns off visibility of bodies in the browser while the script is running.
