lsp-origami-try-enable doesn't start lsp-origami-mode even if the server supports foldingRangeProvider

Using the following (part of) my .emacs:

(use-package lsp-origami
  :ensure t
  :bind
  (:map origami-mode-map
	(("C-c f h" . origami-close-node)
	 ("C-c f s" . origami-open-node)
	 ("C-c f f" . origami-recursively-toggle-node)
	 ("C-c f a" . origami-close-all-nodes)
	 ("C-c f z" . origami-open-all-nodes)
	 ("C-c f g" . origami-show-only-node)
	 )))



(use-package lsp-mode
  :ensure t
  :init
  (setq lsp-keymap-prefix "C-c l")
  :config
  (setq lsp-enable-snippet nil)
  :hook
  (
   ;; (lsp-mode . lsp-origami-mode)
   ;; (lsp-mode . origami-mode)
   (lsp-mode . lsp-origami-try-enable)
   )
  :commands lsp)

;; Python mode

(use-package python
  :mode ("\\.py\\'" . python-mode)
  :interpreter ("python" . python-mode)
  :config
  (use-package python-black)
  :hook
  (
   (python-mode . python-black-on-save-mode)
   (python-mode . lsp)
   (python-mode . show-paren-mode)
   )
  )

I get different behaviour depending on whether I use the lsp-origami-try-enable hook or the two commented hooks (which start origami and lsp-origami explicitly). For example, explicitly starting lsp-origami-mode allows me to fold on a while: inside a function definition, which does not work with just origami.

I think this is actually due to using lsp-mode hook rather than lsp-after-open in the:hook block. I will play around with it a little more, and probably close this issue if it seems to work.
