Hello, I imported the unity package from Releases into my Unity project (2019.4.8f1). It warned me about obsolete APIs, then I got the following error:
Hedera\Editor\Scripts\IvyEditor.cs(282,18): error CS0120: An object reference is required for the non-static field, method, or property 'SceneView.drawGizmos'

Then underneath it:

Some scripts have compilation errors which may prevent obsolete API usages to get updated. Obsolete API updating will continue automatically after these errors get fixed.

Do you know how to fix this?

Thank you!
