Solved Unknown command?!

[adycris]

A problem that I met with these days is that I don't know in skript how to check if a command actually exists or not, without involving permissions and stuff because the only thing that you can do using skript to replace the unknown command that I know right now is by using "if (permission of command command) is not set:". When is not set, it'll also execute the events you want to the commands that does not exist + the commands that doesn't have a permission imposed by the plugin that created the command and I want only to execute the event to the commands that doesn't exists. Any ideas? Here is my skript:

on command:
if executor is not console:
if (permission of command command) is not set:
if executor doesn't have permission (permission of command command):
if {cooldown::%player%} ? now <= now:
set {cooldown::%player%} to 2 seconds later
cancel event
send title "<##CA3818>&lTitle" with subtitle "Subtitle" to executor for 3 seconds with fade in 8 ticks and fade out 5 ticks

- this skript tells the title to the unknown commands + the commands that doesn't have a permission imposed by the plugin that created the command. I want only for unknown commands.. If someone has an idea, it'll be amazin', I think that it's only possible with skript-reflect but if you guys know to do this thing in default skript, it'll be better, it doesn't really matter.. Thankss!

Solved, thanks to @publicjake.github.io on SkUnity's discord:
import:
org.bukkit.event.command.UnknownCommandEvent

on UnknownCommandEvent:
set {_s} to event.getSender()
{_s} is a player
event.message({_})
send title "aa" to {_s}
