Make text Invisible with font-lock-keywords

Question

I'm interested in changing my org-mode buffers to have a better looking logbook. My ideal state to end up in is that text that looks like this:

- State "WAITING"    from "WAITING"    [2018-11-16 Fri 16:00] \\
  description of why this task is still waiting
- State "WAITING"    from "WAITING"    [2018-11-16 Fri 11:20]
- State "WAITING"    from "NEXT"       [2018-11-15 Thu 11:55] \\
  Addressed feedback Bump on 2018-11-19 if not approved yet.

instead is formatted to look like this

- WAITING [2018-11-16 Fri 16:00] \\
  description of why this task is still waiting
- WAITING [2018-11-16 Fri 11:20]
- WAITING [2018-11-15 Thu 11:55] \\
  Addressed feedback Bump on 2018-11-19 if not approved yet.

I've gotten pretty close to what I want with this code:

(defface mjh-subdued `((t :background ,mjh-base03 :foreground ,mjh-base02))
    "Subdued face for text that shouldn't be very visible.")
(font-lock-add-keywords
   'org-mode
   '(
     ("\\(State +\"\\)\\(TODO\\)\\(\" +from.*\\)$"     (1 'mjh-subdued) (2 'mjh-subdued)  (3 'mjh-subdued))
     ("\\(State +\"\\)\\(NEXT\\)\\(\" +from.*\\)$"     (1 'mjh-subdued) (2 'mjh-subdued)  (3 'mjh-subdued))
     ("\\(State +\"\\)\\(WAITING\\)\\(\" +from.*\\)$"  (1 'mjh-subdued) (2 'mjh-waiting)  (3 'mjh-subdued))
     ("\\(State +\"\\)\\(DONE\\)\\(\" +from.*\\)$"     (1 'mjh-subdued) (2 'mjh-subdued)  (3 'mjh-subdued))
     ("\\(State +\"\\)\\(CANCELED\\)\\(\" +from.*\\)$" (1 'mjh-subdued) (2 'mjh-canceled) (3 'mjh-subdued))
 ))

With this, the text isn't invisible, but it is subdued so it doesn't draw much attention. Ideally, I want the text that is currently formatted as mjh-subdued to be invisible (and zero-width).

But I'm stuck. I can't figure out how to add the 'invisible text property to the matched groups. According to search based fontification, I should be able to add text properties for the (matcher . facespec) form, but I can't figure out how I need to get it worked. Changing one of the (1 'mjh-subdued) to (1 (face 'mjh-subdued :invisible t)) does not work. (and breaks what I do have working)

Any ideas on where I should look for this? I tried looking through the source for font-lock-add-keywords, but it's pretty dense.

I can add the code for the other faces if it matters, but they just change the TODO keywords to be colored differently.
