Replace Authorization value with DirectLine secret. See: https://docs.botframework.com/en-us/restapi/directline/

This is a Visual Studio Web Test. You will need to compile the JSON extraction rule class (here: https://gist.github.com/RichardSlater/8669705) and add a reference to that to your project to run the test (each agent in the test establishes a conversation, extracts the conversation ID from the JSON response and subsequently send a message again with the conversation ID).

Please do not load test the DirectLine. It is a shared resource.
