That should probably be similar to the handling of X-Request-PGP:
,----[.gnus]
| ;; handle X-Request-PGP header
| (add-to-list
|  'gnus-header-button-alist
|  '("^X-Request-PGP:" gnus-button-url-regexp  0 t jk/gnus-handle-request-pgp 0)
|  t)
|
| (defun jk/gnus-handle-request-pgp (url)
|   "Fetch PGP key from URL specified in X-Request-PGP header.
