I haven't worked in a team in years. How do I convince people that I want to?

I am currently in the last year of my PhD and applying to a boot camp style academia to industry program. As part of my application I need to describe a recent experience of working successfully in a team. The thing is: I’d love to be part of a team of motivated people and this is one of the reasons I want to leave academia. But my work as a graduate student has not been collaborative at all. Now I wonder what to do: Do I dig up and inflate one of the few small examples of team work that have happened in the last five years or should I be honest and focus on my desire to work with people in the future? Your opinion is very much appreciated. Thank you.
