How to refresh org-mode content?

[TimotheeMathieu]

Hello,

I am trying to refresh the toc of an org-mode file after the headers changed. But it seems that refreshing (by hitting g or r in the treemacs buffer) does not do anything for org files.
Although it works to display newly created files or to remove deletted files.
The only way to update the view of my org file as of now is to reboot emacs.
Am I doing something wrong or is this just not implemented yet?

Here is my treemacs setup (I am trying to setup treemacs as a toc only explorer in org and tex files, I do not really use it to explore files):

(use-package treemacs
  :init
  (with-eval-after-load 'winum
    (define-key winum-keymap (kbd "M-0") #'treemacs-select-window))
  :config
  (progn
    (setq treemacs-display-in-side-window          t
          treemacs-file-event-delay                2000
          treemacs-indentation                     2
          treemacs-indentation-string              " "
          treemacs-text-scale                      0.8
          treemacs-width                           30
          treemacs-width-increment                 1
          treemacs-persist-file                    nil
          treemacs-display-current-project-exclusively t
          )

  (with-eval-after-load 'treemacs
    (treemacs-follow-mode t)
    (treemacs-filewatch-mode t))
)

  :bind
  (:map global-map
        ("M-0"       . treemacs-select-window)
        ("C-x t 1"   . treemacs-delete-other-windows)
        ("C-x t t"   . treemacs)
        ("C-x t d"   . treemacs-select-directory)
        ("C-x t B"   . treemacs-bookmark)
        ("C-x t C-t" . treemacs-find-file)
        ("C-x t M-t" . treemacs-find-tag)))
