Accidentally Deleted Water Content Blueprints

Hello, I’m really new to Unreal, I’ve really only started learning it a few days ago and i was taking a look in to the Water Content Plug-in but in trying to figure out some stuff i messed up some blue prints without even realizing it, one of them, (the buoyancy object example) i completely changed and i deleted it expecting to be able to reinstall the defaults or something like that, Is there any way to reset the plug in? I hope you can help me with this.
