Locust tree flower oil extraction
can be done in an soxhlet extractor?
someone tried?
What solvent have you used?
N-pentane hexane?
clevenger type apparatus is suitable?

I'm waiting for any advice.

There are nearly as many different ways to extract fragrance oils for industrial use as there are fragrances -- even Wikipedia can't keep up: https://en.wikipedia.org/wiki/Essential_oil#Production

Typically, hexane isn't what's needed for fragrances, but the exact procure, for the most important fragrance oils, is generally proprietary.

If you've got some, try some things, keep good notes, and make yourself some money if you can.
