Doom-emacs: Org attach errors (on DND action or after selecting pdfs via +org-attach/file fn)

Hi, when attempting to drag and drop image into emacs (from dolphin into GUI emacs) I am getting Error: (void-function +org-attach:url).
Need surfaced for me to somehow manage attachments as reference to tasks, I discovered Abo-Abo's org-download, which is what Doom's configuration uses as backend, but it somehow doesn't seems to work.
From all attach commands which I found via M-x, only +org-attach/file seems to produce desired result and only with image files (image is embedded into buffer) - with pdf I am getting user-error: Failed to attach file: Symbol’s function definition is void: org-attach--icon. I guess from source that I should get file link with some fancy pdf icon, but I don't.
