Hey guys,  
I am integrating your plugin in a VR app and found and error when building after importing it.

Attached the scenario to reproduce it in a txt file

The objective of this ticket is more to inform about bug than fixing it, because this error just happens when IL2CPP is selected as scripting backend. If Mono is selected, everything goes like in your tutorials.  
If you need more info, just let me know 😄

Hello \<@421694618615283718\>, I didn’t see anything about Convai in the logs.

By importing the Core SDK and importing the VR package, I was able to get the build without any problems.

The problem may be caused by different SDKs if there are different SDKs in your project.

Convai supports IL2CPP for VR.
