Wikipedia's /Lucy (spacecraft) says nothing of propulsion, and it's SWRI home page for the spacecraft http://lucy.swri.edu/mission/Spacecraft.html gives specification and enumerates what's on Lucy’s instrument pointing platform (IPP) , but is silent on things like propulsion, attitude control, navigation, etc. Here are the specifications:
LUCY SPECIFICATIONS
Width: 46.75 ft (14.25 m)
Height: 23.6 ft (7.2 m) or 12.4 (3.8m) when solar panels are stored)
Depth: 9.12 ft (2.78 m)
Diameter of Solar Panels: 23.9 ft (7.3 m)
Dry Mass (unfueled): 1810 lbs (821 kg)
Wet Mass (fueled): 3417 lbs (1550 kg)
Power: 504 watts at the furthest encounter
Fuel is 47% of the mass, so this is a "flying fuel tank"-class spacecraft, with a larger fuel fraction than the electrically propulsed DAWN but well below the 60 to 70% of the winners.
This answer to What propulsion will Lucy use for its deep space maneuvers? cites only an article about a different mission that mentions conventional propulsion for Lucy in passing, then speculates further.
Question:
- Where can I read about Lucy's complete propulsion system?
- If the answer is "you can't" then please answer instead "Why not, I paid for it!? (a little at least)"

update: I found the words "bipropellant main engine" in Refining Lucy Mission Delta-V During Spacecraft Design Using Trajectory Optimization Within High Fidelity Monte Carlo Maneuver Analysis (Preprint) AAS 19-614 J. V. McAdams et al. (2019??) along with some uncertainties in delta-v that might offer some clues.
