Just hatched an idea. And yes, it would involve an AI generated voice.

Okay so what is the current canon for force ghosts in Star Wars? TROS confused it.

As of ROTS I thought Qui-Gon was the only one who had any ability to persist after death and even then only vocally. Then, Yoda and Ben were able to go further than that under his tutelage. And then they sort of ‘helped’ Anakin become a Force ghost too. And idk, maybe could’ve helped any subsequent Jedi who didn’t know the tricks.

Then in TROS, we hear voices of many Jedi. (Implausibly though, only those the audience knows and not the thousands that lived since the ancient texts about communing with dead Jedi were written.)

Then, in Kenobi we see Qui-Gon’s ghost visually. But maybe he’d just taken a while to work it out; this isn’t as confusing as TROS.

So here’s the idea. It doesn’t totally solve things but helps.

Rey bemoans her difficulty following the Jedi texts’ instructions on communing with dead Jedi. We add a new line, “Luke wrote about it.” This cements the directions she is following within the lineage of Qui-Gon -> Yoda and Ben -> Luke.

The remaining issue would be Jedi whom were not privy to this speaking to Rey during the climax.
