Python API: DataReader/DataWriter find_by_name(): What is name?

I would like to make use of `find_by_name()` byt I can't determine how to set a name for the reader. Passing the topic name or type name does not work.

`find_by_topic()` and `find_all_by_topic()` does work using topic name, and probably is sufficient for my needs. I'm just trying to understand the API.

Hi, because the Connext Python API's documentation is not up to par (its new and still being worked on), you should confer the docs of a different language to find the information for the equivalent method.

In this case, it's DDSSubscriber::lookup_datareader_by_name:

https://community.rti.com/static/documentation/connext-dds/7.1.0/doc/api/connext_dds/api_cpp/classDDSSubscriber.html#ac76625bb6c883c6e90782dfef715f320

You'll see that it uses the EntityName QoSPolicy.
