Unable to invoke non-HTTP triggered functions with cardinality: many using admin API

Question

As per our docs, there is a way for customers to test their functions locally using core tools and the admin API.

We received an issue related to this from a customer using a Python Event Hubs function regarding lack of clarity on the schema expected for the request body. They were able to get it to work when the function was set to cardinality: one, but not with cardinality: many.

I tried testing both the Kafka and Event Hub extensions with cardinality: many, but I was also unable to get it to work, even after some help from the Python-worker team (cc: @gavin-aguiar). I was unable to get it to work in other languages (Node, C#).

I am still unsure if there is way to do this using the admin APIs, or this is unsupported. If it is supported, an improvement in the docs would be helpful.

Additional context

There are existing issues about this on the Python-worker repo as well.
