I personally think mentioning both the texts AND Leia in such a tight space feels too forced, and like, wouldn’t the texts themselves show her how? It’s a neat idea to have Leia be involved, but she’s already very involved in Ben’s redemption as it is, she sacrifices herself to reach out to him, and with the added shot of the medal it’s also implied she had a hand in Ben’s “memory” of Han. I think is fine if the Force Heal is left as a personal moment between Rey and Kylo/Ben, and it gives the ancient knowledge Rey decided to preserve a moment to shine in this film.
