Add Product to User Via REST API

We are trying to leverage Adobe User Management APIs to add new users and associate Products with them.

We found this document in the Adobe Developer Portal. 

https://adobe-apiplatform.github.io/umapi-documentation/en/

While in this document, the UserActions work fine ((https://adobe-apiplatform.github.io/umapi-documentation/en/api/ActionsCmds.html)).

but we are not able to assocaite a product with this newly created user. The Product APIs have been deprecated and we have not been able to find an alternate. 

Here are the APIs which are showing as deprecated.

Can we get some help ?

Thanks,
