How will Lucy "make use" of a deep space atomic clock?

Question

The entry for Lucy in Wikipedia's Selection of Discovery Mission 13 and 14; Finalists says:

The mission will make use of the Deep Space Atomic Clock.⁸¹

The Universe Today article says only:

NASA has also offered an additional \$5 to \$30 million in funding if mission planners choose to incorporate a laser communications system, a 3D woven heat shield, a Deep Space atomic clock, and/or ion engines.

and the linked Deep Space Atomic Clock article does not mention Lucy, nor is the mission mentioned in any of the questions below nor their answer.

Question: So I'd like to ask: How will Lucy "make use" of a deep space atomic clock?

Deep Space Atomic Clock Q&A that don't currently mention Lucy:

• Where would one deploy deep space atomic clocks?
• How does an onboard atomic clock help interplanetary navigation?
• Help understanding exactly how an atomic clock facilitates “self-driving spacecraft” when paired with an onboard camera?
• Why does the Deep Space Atomic Clock have such a short mission?
• How high is the first Deep Space Atomic Clock orbiting? Does it receive radiation equivalent to that in deep space?
• How far from earth have atomic clocks (or ultra-stable oscillators) been placed and monitored?
