Retrieve the records persisted to H2 DB

Hi,
I am using camunda-bpm-wildfly-7.14.0. I have deployed my own web application (.war) file to the wildFly server and persisting data while starting the process using

engine-rest/process-definition/key/myObject/start

I know I can get the user data from camunda with

/camunda-rest/engine-rest/user

And a specific user with the following API

/camunda-rest/engine-rest/user/demo/profile

What are my options to retrieve the records persisted to the H2 DB while starting the process (myObject)?
