Thanks @megreyhair. I'm glad I now know that, just in case. I was able to confirm the manual charging door release function, but sadly not the rear seat ejection one, in the Owner's Manual, on Page 563, after stepping through 134 of 136 uses of the word "manual" in the manual. The nondescript picture that they illustrate that handle, taken from a stand on your head and look up perspective would not have been much help. I'm over 3 years into ownership of my 2018 Clarity, and still discovering new stuff about it.
