Hi Everyone!
I need to synchronize my Mathematica 12.0 with Unity 2021
Following the instructions in this video
[Build Your First Game in Wolfram Language with Unity Game Engine: Live with the R&D Team ][1]
and this manual https://reference.wolfram.com/language/UnityLink/guide/GettingStarted.html
I've Installed and activated Wolfram Engine 12.2 but have no idea how to get that wolframUnity.package ( that need's to be added to Unity Project )
Also, when i run this command Needs["UnityLink`"] giving me this error : 
i assume that UnityLinks needs to be installed after running it
