Kubejs sendTriggerFor

I don't understand how sendTriggerFor works
`
ItemEvents.rightClicked(event =>{
    const da  = new ParticleEmitterInfo(new ResourceLocation('aaa_particles', 'cursefault')); 
    da.position(event.player.x, event.player.y, event.player.z);
    if(event.item.id === 'minecraft:wooden_sword'){
        AAAParticles.addParticle(event.player.level, false, da)
    }
}) 
 `
