How to use prefix C-SPC instead of prefix C-h, for `which-key-mode-map`?

Question

I'd like to change the C-h prefix to C-SPC and so I added the following to my init.el, but it has no effect.

(define-key which-key-mode-map (kbd "<C-SPC>") 'which-key-C-h-dispatch)

Help understanding how to make this change would be appreciated. Thanks.

@Drew: it might be related but it seems like a fairly different circumstance (doesn't mention the same error, and it's specific to the which-key package). — Stefan, Commented Mar 27, 2020 at 21:24
@Stefan: OK; I wasn't sure. Seemed to be about replacing one prefix key with another. — Drew, Commented Mar 27, 2020 at 23:39

Ctrl is 2^26, SPC is 0x20, so C-SPC is 0x4000020.

Set variable help-char to C-SPC: (setq help-char #x4000020)

Or (aref (kbd "C-SPC") 0) if you want to do that in a way a human could read. (Not that it's not good background info, but I think that referring to keys in your init file with just the raw numbers would be slightly mad.)
