"Visualize Points" button creates errors

[ByteSz]

Unity Version

2021.3.28f1 LTS

Description

When trying to use the point visualization feature in the plugin, and pressing the button to do so in the editor GUI, the targeted model disappears and an error is thrown.

Error

"ArgumentException: The Object you want to instantiate is null."

Cause

From some initial investigation, it seems this is due to the "_point" prefab being assumed to exist in the resources folder. This will not be the case in fresh projects, at least in Unity 2021.3 LTS.
