How can I get the shared Containers Elements and their Values using the API?

I uploaded a project that has shared Containers that are reused in several UserPaths.
How can I get element values for the shared containers, in NeoloadWeb using the API?

To be able to get percentiles for the shared Containers.
Percentiles for shared Containers/transactions, do exist in the XML report (produced locally).
Why not in NeolodWeb, since I uploaded the same project?
shared Containers are also not returned via the API. Why?

Thank you,
