Affinity Photo Scripting with GUI Scripting?


I try to get access to the internal macros of Affinity Photo with either the accessibility tools of Apple or Gui Scripting.
The problem is I can not find a way to address and navigate to the library of Affinity Photo and scroll through the different macros and the mark/start the liked one of the list.
I there a way to to this? Affinity told me they don´t plan to integrate scriptability shortly as for instance Pixelmator and Photoshop has.

It would be great to avoid Pixelmator and Photoshop.

Best regards and many thanks
