Transaction ID

I cannot find a way to capture the transaction ID and PayPal status of a submission when using PayPal Express. I have another form which captures it in the submissions (I can see it in the submissions field listing) but when making a new form I cannot find a way to add it and I can’t find the field where I capture it in my other form.

Is this done through the PE plugin itself or do I need to set this up on PayPal? I can’t find any info about this on the NF documentation.
