If it's been over a month, she may not be able to activate it.
How do I activate my Global Entry card prior to use at NEXUS/SENTRI lanes?
Activate your card within 30 days of receipt or you will be unable to use your card at the Trusted Traveler lanes.
But you are correct, activation is not required if she's not planning to to use it.
How do I know if I need to activate my membership card?
If you have a Global Entry membership, your card is only required if you are traveling by land into the United States from Canada or Mexico.
