Solved If player used /tp and teleported

Hi, I'm making a event where if the player teleports via /tp and successfully teleported something happens (in this case; a sound effect).

How can I do this?
I tried:

Code:

    // Play sound on teleport
    @EventHandler
    public void onTp(PlayerCommandPreprocessEvent e) {
        Player p = e.getPlayer();
       
        if(e.getMessage().startsWith("/tp")) {
            if(getConfig().getBoolean("playerTP")) {
                p.playSound(p.getLocation(), tp, 1, 0);
            } else {
                // Do nothing
            }
        } else {
            // Do nothing
        }
    }

But obviously that only checks if the player just typed in /tp, it doesn't check if the player successfully teleported.

I've also tried using the PlayerTeleportEvent but that triggered when the player spawned aswell, not really what I want.

What's the correct way of doing this?

Nvm, fixed with:

Code:

    // Play sound on teleport
    @EventHandler
    public void onTp(PlayerTeleportEvent e) {
        Player p = e.getPlayer();
       
        if(e.getCause() == TeleportCause.COMMAND || e.getCause() == TeleportCause.PLUGIN) {
            if(getConfig().getBoolean("playerTP")) {
                p.playSound(p.getLocation(), tp, 1, 0);
            } else {
                // Do nothing
            }
        } else {
            // Do nothing
        }
    }
