Sorry for being chaotic, my post for someone who doesn’t use the app might be confusing.
What I am looking/want to achieve is really similar to what already exists.
So basically I want to get a link in such (current) form
[EEG Frontal Asymmetry in Dysthymia, Major Depressive Disorder and Euthymic Bipolar Disorder](zotero://select/items/1_J3J6DJ28)
My problem is that with the release of Zotero 6 I started using a built-in PDF reader in Zotero. I still can get link via Hook from Library view as before, but I cannot get link to item when I am viewing this item as pdf in the Zotero window.
Zotero offers quick copy functionality (shift + cmd +c) which copies an item in the selected bibliography style.
Via this functionality, I am able to copy the link to the item even when I open it as pdf (so reader pane is active and no longer page with collections)
[EEG Frontal Asymmetry in Dysthymia, Major Depressive Disorder and Euthymic Bipolar Disorder](zotero://select/items/1_J3J6DJ28)
When someone has different settings for quick copy, that person just get a formatted bibliography position (not markdown link) and in this sense, I was wrong because it will not work for everyone
My question above was not the request to developers @LucB for a new feature but more bump to the other users who use/know AppleScript, commented here and could make my idea working 
With specific setting the Zotero windows after shift+cmd+c will output a nice formatted markdown link with Zotero URI, what I need to know is only how to simulate those keystrokes on active Zotero windows through hook via AppleScript
About opening PDF in Zotero: before (I Zotero 5) I was able to open pdf by subtituting part of Zotero URI, know I dont know if this still works, bc I dont use it and I am not sure I am needing this
For me now enough is if I could get hooked what this quick copy shorcut gives me (it doesnt need processing it is alread markdown + URI)
