How to capture the User response through Human Intervention in AI Agent

Summary:

We are building a Workflow Agent that could read a Document through MultiFileProcessor and extract the Parts,Quantity and Other details from the Document and display them in the tabular format with the option for the user to select the needed Parts. Once the Parts are selected we want the user to proceed with Quote creation by passing the selected parts to be added into the Quote as Line Items.
We are able to display the table and the option for user selection in the table, but subsequent steps of extracting the selected data from the Table in UI and passing it to the Quote creation tool is not captured or processed.
