Dynamaps not found

Hello experienced people !!
I used dynamo before and i recently heard of dynamips which could really help me in my student project . i went to my view tab in dynamo but couldnt find dynamips there . i want to get started with dynamips.
For your information , i am using Revit 2020 and my dynamo version is Dynamo core 2.1.0.7500 and Dynamo revit 2.1.0.7733

Have you installed it from the package manager?
