Custom Kill animation

Did you manage to make it works i kinda want to make a simular thing ?

I am basically doing a power that move a premade vfx to the fort_character position and is being enabled for 10 seconds but it does not teleport and even activate there is the code :

    using { /Fortnite.com/Devices }
    using { /Verse.org/Simulation }
    using { /UnrealEngine.com/Temporary/Diagnostics }
    using { /Fortnite.com/Characters }
    using { /UnrealEngine.com/Temporary/SpatialMath }

    powers := class(creative_device):
        
        @editable SignalRemoteGrey : signal_remote_manager_device = signal_remote_manager_device{}
        @editable VFXDevice : vfx_spawner_device = vfx_spawner_device{}
        
        
        HandlePrimaryButton( P : agent) : void =
              spawn:
                    StartEffect(P)
                
               

        StartEffect(P: agent)<suspends> : void =
            if (F := P.GetFortCharacter[]):
                if (VFXDevice.TeleportTo[F.GetTransform().Translation, F.GetTransform().Rotation]):
                    VFXDevice.Enable
                    spawn:
                        EndEffect()
                        
        EndEffect()<suspends> : void = 
            Sleep(10.0)
            VFXDevice.Disable 
 
            
            
        HandleSecondaryButton( P : agent) : void =
            if (f := P.GetFortCharacter[]):
    

        OnBegin<override>()<suspends>:void=
                SignalRemoteGrey.PrimarySignalEvent.Subscribe(HandlePrimaryButton)
                SignalRemoteGrey.SecondarySignalEvent.Subscribe(HandleSecondaryButton)

Would apreciate some help im very new to verse and uefn.
