How to use FLATTEN function in query function

Below in my query result:

Snapshot of Google Sheets

In the above table "Form Response" table is the response received in Google Sheets from Google Form.
I want to convert "Form Response" table to "Desired Result" Table.
I used FLATTEN & SPLIT functions to convert column Card data with one name in one cell.
I manually entered Timestamp date in Desired Result Table.

I need the Timestamp information automatically in Desired Table
