Hello All, Posting here because I have a issue setting up the Lumin SDK with Unity. I can't browse the Lumin SDK from the External Tools in the Unity Preferences, the option does not show. So I can't select the Lumin Platform from the Build Settings (it doesn't show neither) https://ibb.co/ySm15ks (Screenshot) I tried (twice! with Unity 2019.2 & 2019.3) to follow the steps as described on ML website (https://developer.magicleap.com/en-us/learn/guides/unity-setup) but can't figure out what I'm missing... I can perfectly run the demo scenes from the ML Examples, even with Zero Iteration running from my device. But can't manage to add the SDK to actually build these apps. What am I missing? Thank you.
