They likely didn't.
The Egyptians recorded many things, including excuses for missing work, with incredible detail. They never once recorded how they built the pyramids.
Either religious/spiritual/ritualistic reasons prevented them from doing so, or they didn't build them. Either way, they didn't record it and probably didn't speak of it.
Thank-you.
Papyrus describing laying is unlikely unless it somehow related to accounting.
But, do you know the Shabakti stone? That is supposedly a copy of a first dynasty papyrus by the Nubian pharaohs. While likely to be embellished, no reason not to believe. Helps describe the role of Ptah, the god of design.
But I doubt there is any indication whether this was for maintenance work, or original construction.
Pharaohs were always embarking on patch-up and upgrade projects on ancient stuff, and tagging everything they touched with their personal cartouches (often having their predecessors' chiseled out, first). So it is very hard to know who really built what, or when. The Sphinx is officially ascribed to a Pharaoh who leaned a stela on it bragging about maintenance work he had ordered (a thing there are also a lot of).
But they never tagged pyramids.

implied somebody else built the pyramids.

What are you implying here, exactly? That humans didn't build them at all?
That said, a sibling content to yours provided recently discovered evidence that the quarrying of stone for the pyramids was recorded.
