Unity Reflect Develop "Importer" package manager

Hello,

In the former version of unity/unity reflect (and before the distinction between develop, review and collaborate). I used the unity reflect preview from the package manager to import models in a scene.

The previous project I have working on an older version of that package (and older unity version) seems to work, but if i try to start a new project on unity 2020 LTS, i can import the package but it directly generates errors and following Windows->unity Reflect tab is not created?

Is it due to new developpments which tends to only use the actual viewer template you download from the git or is there specific requirements to setup the importer?

Best regards,

 

I would appreciate a response to this
