How to get in or out of an chipkaart-gated station with an e-ticket? [duplicate]

I recently purchased tickets for an international trip from France to the Netherlands. The itinerary​ included an international ticket to Rotterdam, and a local ticket to my final destination. I accessed the ticked via the NS International app on my phone.

Everything went fine until I arrived at my destination, Voorschoten station. This was not a large station, and I found a line of people scanning their OV Chipkaart to open a gate and exit. There didn't appear to be any way out without a card. I didn't have one, so I made a dash behind someone else when the next train arrived.

Now I need to make my return trip from the same station. Is there a legal, standard way to use my electronic ticket to open the OV card gate?
