How do you introduce yourself to HCPs who have never interacted with a MSL?

I'm a new MSL straight from academia and hoping for some guidance. We have small territories are being asked to find community KOLs rather than just big name academics.

Some of these physicians are in small private practice and have only ever interacted with reps. How do I compliantly tell them what I can do for them? My product is preapproval so I can't just come out and say, "want to see our data hot off the presses". I can't feed their office either, so how do I get them to spend time on me?

Thanks for any feedback!
