Customer would like to run an agent to access data refer to following link:
https://help.hcltechsw.com/domino-leap/1.1.3/direct_access_domino_data.html

The scenario is as below:
1. Create a new document via web browser.
2. Enter value for some fields/items in the new document. Do NOT save the new document.
3. Run an agent.

Customer needs the function/ability that the agent get the current new document object so as to get the value of all items in the new document.

Note: not sure whether this requirement can be achieved by JS object. However, customer hopes that LEAP itself can provide this function, rather than customizing additional code.
