Email my LOCI to....?

I want to write a LOCI after being waitlisted, and the general consensus seems to be that I should write directly to my admissions officer rather than the admissions office. I can't find my officer's contact info on my portal, and idk which region I'm technically considered to be (it's complicated)

Sooo what should I do? Should I email the office and ask who my admissions officer is, or is that too weird??? Or should I just email the office directly?

I'm definitely overthinking this, but oh well!
