Sounds like you only have this one opportunity to help your career, so why not go for it. If they don't query you about your physical condition, volunteering it is at your option.
Map out the bathrooms, do wear some depends, and the experience may/will help with the phobia, and mental aspects of your urgency. I think you may surprise yourself.
Talk to your GI, there are lots of medications and even suppositories that can ease not only your flare, but also potential urgency.
Good luck, and let us know how it goes.
