Trigger to respond to clipboard changes

[MBaas]

QuickMacro has a trigger "Clipboard copy" - I would like to write code in LA that responds to clipboard changes. How can that be done?
I checked "Other Triggers", found the pointers to WinEventHook.WinEventHook - but I can't find anything related to clipboard changes in the list of Event Constants - so maybe it uses a different mechanism. I'm afraid I don't know these mechanisms well enough - so would appreciate some help

Click menu TT -> Other triggers.
Insert this text near the end, before the last }.
Click Run.

    void ClipboardTriggers() {
        var w1 = WndUtil.CreateMessageOnlyWindow(static nint (wnd w, int msg, nint wp, nint lp) => {
            if (msg == api.WM_CLIPBOARDUPDATE) {
                print.it("Clipboard trigger");
                
                //if want to get clipboard text, do it with a delay, else it may interfere with other clipboard programs or scripts
                timer.after(100, _ => {
                    var s = clipboard.text;
                    print.it(s);
                });
            }
            return api.DefWindowProc(w, msg, wp, lp);
        }, "#32770");
        api.AddClipboardFormatListener(w1);
    }
    
    unsafe class api : NativeApi {
        [DllImport("user32.dll", EntryPoint = "DefWindowProcW")]
        internal static extern nint DefWindowProc(wnd hWnd, int msg, nint wParam, nint lParam);
        
        internal const int WM_CLIPBOARDUPDATE = 0x31D;
        
        [DllImport("user32.dll")]
        internal static extern bool AddClipboardFormatListener(wnd hwnd);
    }

Thank you - that's exactly what I needed!
