DynamoViewport View Extension Installation fails

Packages
1

Hi everyone,
I found this video from @Kulkul which demonstrates the installation process of the DynamoViewport extension : Build Dynamo Viewport Extension from Source - YouTube
(Github link: GitHub - alfarok/DynamoViewport: A simple view extension for visualizing Dynamo geometry. by @alfarok )

So basically I got errors on my Visual Studio when I start a Dynamo build.

I tried to pass this step and build the Viewport extension directly from Visual Studio, I then copied/pasted the Viewport package folder to the packages folder as indicated in the github link, i could see the extension in my View list in Dynamo.
But it gives me an error as soon as I try to launch it.
Below are the error messages from Dynamo (Revit 2019, Dynamo 2.0.3)

What am I doing wrong ?
Thanks

The extension relies on a new version of Dynamo. The readme states Dynamo 2.7, you can try to remove the use of the function - CloseExtensioninInSideBar - which doesn’t exist in Dynamo 2.0.3

or switch to an older commit in the github repo and build that.

I think this branch should work for you:
