The Debugger service provides the API that allows users to collect run-time information from a running application, without stopping or slowing it down and without modifying its state.
The returned connection object should not be used directly; instead it should be passed as an argument to the constructor ofController2Client.
The optionaloptionsargument may be used to configure aspects of the returnedController2Connection. Expected options are any of the types in the following option lists:
