I already explained a way. I since looked up PIC chip outputs, they
can source AND sink, up to 50 mA either way.

20 mA. Not 50 mA.

True, it seems. I had the misfortune to first bump into this:

"PIC pins will sink (drive to ground) or source (output to a ground-
connected load) 50mA."

The page is incorrect.

20 mA is enough though, assuming it can sink as well as source.

The PIC can sink and source @ 20mA.
