CivilConnection IS NOT for Dynamo for Civil 3D, it is for Dynamo for Revit, Read the documentation

I have installed the “CivilConnection2020” package, but as you can see in the image it has not been added within the “Add-ons” and besides that, when opening a script that contains nodes from this package, it does not recognize them and the notification that the “civilConection2020” package needs to be installed. In the image you can see well that if it is installed.
Please could you help me solve this.

Dynamo core
Dynamo Civil 3D
