Is anyone applying to a law school that allows you to add an optional essay in regards to certain fellowships they may offer? (Aka financial aid)

If so... Do you have any advice as to what to include in the essay? I'm not generally interested in the fellowship, but I am interested in the financial help.... At a crossroads!

Example of "fellowships" - working at the law library, special education advocacy clinic, public service admissions ambassadors etc.

Thanks for the help friends!
