Part numbers not saved to the schematic or board files?

[jmsaltzman]

Is your feature request related to a problem? Please describe.
I have successfully exported files for PCBA (!!) but I'm not sure how to get the LCSC part numbers in my files independent of the plugin. I see the part numbers in the plugin window, and they exported fine for my JLCPCB order, but I do not see them as properties of components.

Describe the solution you'd like
I'd like to know how to get the part numbers as footprint properties (or symbol properties?).

Describe alternatives you've considered
I could manually enter them all, and there aren't many, but I imagine there's a way I'm missing.

Additional context
I thought "Export to Schematic" would add the part numbers as symbol properties, but when I specified the schematic file, I got this message, and the LCSC's are not in the resulting file:
"2024.04.04 16:47:03 - INFO - _update_schematic - Added LCSC's to C:\Users\jmsal\Dropbox\KiCad\CH224_breakout_jms_2\CH224_breakout_jms_2.kicad_sch(maybe?)" <-- "maybe" hmm... :)
It was odd that the save file browser suggested the filename "jms_2.kicad_sch" instead of the longer one; I wonder if my project file's underscores were unexpected.
I had manually added LCSC properties for two footprints in PCBNEW before using your plugin; I wonder if their presence was unexpected and caused an issue. They did appear when I first ran your plugin though-- it was great to see them pipe through.
FWIW I'm running KiCAD 8.0.1 on Windows 10 (latest).

I also want to add: this is AMAZING work and I am so, so impressed! THANK YOU for your thoroughness and generosity!
