How to get the title of the taskbar thumbnail button being clicked?

Question

How I could get the title or HWND of the window in which her taskbar button thumbnail is being clicked?

What I tried: using CBTProc i listen to HCB_ACTIVATE , and when the message is received I call UIAutomation reading ElementFromPoint

the problem is... sometimes it works to get the title and sometimes it gets another thing than the title , when this happens title are blank and classname is SysListView32 .

I think this happens when the call to HCB_ACTIVATE is received and the thumbnail already disappeared, then ElementFromPoint get another thing than the window thumbnail.

I would like to not use a global hook in CBT, there's any other way to achieve this task?

std::wstring AccWindowFromPoint()
{
    BSTR name = NULL;

    if (SUCCEEDED(CoInitialize(NULL)))
    {
        CComPtr<IUIAutomation> automation;
        if (SUCCEEDED(automation.CoCreateInstance(CLSID_CUIAutomation8))) // or CLSID_CUIAutomation
        {
            POINT pos{};
            GetCursorPos(&pos);

            CComPtr<IUIAutomationElement> pElement;
            if (SUCCEEDED(automation->ElementFromPoint(pos, &pElement)))
            {
                pElement->get_CurrentName(&name);

                UIA_HWND uia_hwnd = nullptr;
                pElement->get_CurrentNativeWindowHandle(&uia_hwnd);
                BSTR classname = nullptr;
                pElement->get_CurrentClassName(&classname);

                RECT rect;
                pElement->get_CurrentBoundingRectangle(&rect);

                Print("[accwindowfrompoint]"
                    "\nname: ", name,
                    "\nclassname: ", classname, "\n");
            }
            else
                Print("[AccWindowFromPoint] failed to get ElementFromPoint\n");
        }
        else
            Print("[AccWindowFromPoint] failed to CoCreateInstance\n");
    }
    else
        Print("[AccWindowFromPoint] failed to CoInitialize\n");

    //CoUninitialize();

    if (name == NULL)
        return L"";

    std::wstring wstrName(name);

    return wstrName;
}
