Capture the timestamp when a form is submitted

Summary:

I need to capture the timestamp when a form is submitted.

• The form has two required fields.
• I've created a property to capture the timestamp.

I want to configure this in Message Scenarios, but I have two questions:

1. Which trigger condition should I choose?
2. Is it correct to use one of the required properties to ensure the message scenario triggers correctly? (Blocking Conditions)
