How to create the set of product?

Sorry for my question, but how do I create sets with NopModularProducts V2?

I installed the plugin in nop 4.10
I copy the views
I can create a modular product (product template)
I can see my modular product in the list of modular product.

But, I do not find how / where to compose my set.  There is no new section in the product page or Add button in the list of modular product.

Thank you

Erik

1. Create Grouped product
2. Add simple products in Grouped product
3. Change the template for Grouped product (select of on modular templates)
