selectrum posframe

[DarkBuffalo]

Hello,
First of all thank you for this package.

using posframe and selectrum, dimmer doesn't seem to recognize the posframe buffer.
do you have an idea ?

  (p! selectrum
    :init
    ;; always show a certain amount of candidates
    (setq selectrum-max-window-height 15)
    (setq selectrum-fix-vertical-window-height t)
    ;; selection face should extend to the screen edge
    (setq selectrum-extend-current-candidate-highlight t)
    (setq selectrum-display-action '(display-buffer-show-in-posframe)) ;selectrum on posframe
    :config
    (selectrum-mode 1)

    :general
    (leader-keys
      "R" 'selectrum-repeat))


  ;; [[https://github.com/radian-software/selectrum/wiki/Additional-Configuration#display-candidates-in-a-posframe][selectrum on posframe]]
  (defun display-buffer-show-in-posframe (buffer _alist)
    (frame-root-window
     (posframe-show buffer
                    :min-height 15
                    :min-width (frame-width)
                    :internal-border-width 1
                    ;;:internal-border-color (face-attribute "#123" :background nil t)
                    :left-fringe 8
                    :right-fringe 8
                    :poshandler 'posframe-poshandler-frame-center)))
