Clear all Windows 11 notifications with a short-cut key

Question

I would like to have a short-cut key to clear all Windows 11 notifications using Autohotkey v2. This question was asked before but the answer given was for Autohotkey V1.

You can try the following code(F11 to clear):

CreateClass("Windows.UI.Notifications.Management.UserNotificationListener", IUserNotificationListenerStatics := "{FF6123CF-4386-4AA3-B73D-B804E5B63B23}", UserNotificationListenerStatics)
DllCall(NumGet(NumGet(UserNotificationListenerStatics+0)+6*A_PtrSize), "ptr", UserNotificationListenerStatics, "ptr*", listener)    ; get_Current
DllCall(NumGet(NumGet(listener+0)+6*A_PtrSize), "ptr", listener, "int*", accessStatus)  ; RequestAccessAsync
WaitForAsync(accessStatus)
if (accessStatus != 1)  {

    msgbox AccessStatus Denied
    exitapp

}

F11::
    DllCall(NumGet(NumGet(listener+0)+10*A_PtrSize), "ptr", listener, "int", 1, "ptr*", UserNotificationReadOnlyList)   ; GetNotificationsAsync
    WaitForAsync(UserNotificationReadOnlyList)
    DllCall(NumGet(NumGet(UserNotificationReadOnlyList+0)+7*A_PtrSize), "ptr", UserNotificationReadOnlyList, "int*", count) ; count
    loop % count    {

        DllCall(NumGet(NumGet(UserNotificationReadOnlyList+0)+6*A_PtrSize), "ptr", UserNotificationReadOnlyList, "int", A_Index-1, "ptr*", UserNotification)    ; get_Item
        DllCall(NumGet(NumGet(UserNotification+0)+8*A_PtrSize), "ptr", UserNotification, "uint*", id)   ; get_Id
        DllCall(NumGet(NumGet(listener+0)+13*A_PtrSize), "ptr", listener, "uint", id)   ; RemoveNotification
        ObjRelease(UserNotification)

    }
    ObjRelease(UserNotificationReadOnlyList)
    DllCall("psapi.dll\EmptyWorkingSet", "ptr", -1)

return


CreateClass(string, interface, ByRef Class) {

    CreateHString(string, hString)
    VarSetCapacity(GUID, 16)
    DllCall("ole32\CLSIDFromString", "wstr", interface, "ptr", &GUID)
    result := DllCall("Combase.dll\RoGetActivationFactory", "ptr", hString, "ptr", &GUID, "ptr*", Class, "uint")
    if (result != 0)    {

        if (result = 0x80004002)
            msgbox No such interface supported
        else if (result = 0x80040154)
            msgbox Class not registered
        else
            msgbox error: %result%
        ExitApp

    }

    DeleteHString(hString)

}

CreateHString(string, ByRef hString)    {

    DllCall("Combase.dll\WindowsCreateString", "wstr", string, "uint", StrLen(string), "ptr*", hString)

}

DeleteHString(hString)  {

    DllCall("Combase.dll\WindowsDeleteString", "ptr", hString)

}

WaitForAsync(ByRef Object)  {

    AsyncInfo := ComObjQuery(Object, IAsyncInfo := "{00000036-0000-0000-C000-000000000046}")
    loop    {

        DllCall(NumGet(NumGet(AsyncInfo+0)+7*A_PtrSize), "ptr", AsyncInfo, "uint*", status) ; IAsyncInfo.Status
        if (status != 0)    {

            if (status != 1)    {

                DllCall(NumGet(NumGet(AsyncInfo+0)+8*A_PtrSize), "ptr", AsyncInfo, "uint*", ErrorCode)  ; IAsyncInfo.ErrorCode
                msgbox AsyncInfo status error: %ErrorCode%
                ExitApp

            }

            ObjRelease(AsyncInfo)
            break

        }

        sleep 10

    }

    DllCall(NumGet(NumGet(Object+0)+8*A_PtrSize), "ptr", Object, "ptr*", ObjectResult)  ; GetResults
    ObjRelease(Object)
    Object := ObjectResult

}
