Hi Edward,
I recommend taking PM Prepcast course it explains in detail how to prepare for this phase. As a copy editor I also used AI, just to make sure I had covered all the areas. I know this part can seem daughting as there is no obvious feedback loop so you are left wondering if you have delivered enough.
Firstly if you followed the guidence of trainner such as prepcast and you use AI as a copyeditor you should be fine, PMI are not trying to fail you, just remember they are looking for evidence that you have lead projects through multple phases. So its important that you can show this., also remember in case they do audit make sure its in a language that also the people who can confirm the experince understand so not turn it into a full PMI guide.
