Hi,
1. In snapshot layout go to the corresponding step.
2. In the request of the recording snapshot you should see urn:uuid:3b0b011f-1086-467e-8230-293a20e38feb 3. Switch to Response
4. There you can see the same value but it is not as Message ID. Most probably it will be "Relates To".
5. Double-click the value and you will see a window next to it will automatically go to the value.
5. Right-click the new place where you see the value located and select save value in parameter.
Kind regards,
