1.15.2 Help with packets and Particles

So, I have a problem I want to remove the sweeping particles on the client side. I have a piece of code but it not working and I am quit new with packets.
Can someone help me ?

Code (Java):

    @EventHandler
    public void onPlayerJoin(PlayerJoinEvent e) {
        Player player = e.getPlayer();
        CraftPlayer cP = (CraftPlayer) player;
        PlayerConnection pC = cP.getHandle().playerConnection;
        pSP = new PacketsSoundsParticles(pC);
        player.getAttribute(Attribute.GENERIC_ATTACK_SPEED).setBaseValue(100);
    }

Code (Java):

package fr.arkeidos.heozitems;

import java.lang.reflect.Field;

import org.bukkit.Particle;

import net.minecraft.server.v1_15_R1.MinecraftKey;
import net.minecraft.server.v1_15_R1.Packet;
import net.minecraft.server.v1_15_R1.PacketPlayOutNamedSoundEffect;
import net.minecraft.server.v1_15_R1.PacketPlayOutWorldParticles;
import net.minecraft.server.v1_15_R1.PlayerConnection;
import net.minecraft.server.v1_15_R1.SoundEffect;

public class PacketsSoundsParticles extends PlayerConnection {

    public PacketsSoundsParticles(PlayerConnection originalConnection) {
        super((originalConnection.getPlayer().getHandle()).server, originalConnection.networkManager, originalConnection.getPlayer().getHandle());
    }

    public void sendPacket(Packet<?> packet) {
        if (packet instanceof PacketPlayOutNamedSoundEffect) {
            PacketPlayOutNamedSoundEffect p = (PacketPlayOutNamedSoundEffect)packet;
            try {
                Field soundEffectField = p.getClass().getDeclaredField("a");
                Field minecraftKeyField = SoundEffect.class.getDeclaredField("b");
                soundEffectField.setAccessible(true);
                minecraftKeyField.setAccessible(true);
                SoundEffect soundEffect = (SoundEffect)soundEffectField.get(packet);
                MinecraftKey key = (MinecraftKey)minecraftKeyField.get(soundEffect);
                if (key.getKey().toLowerCase().contains("entity.player.attack"))
                    return;
            } catch (Exception e) {
                e.printStackTrace();
            }
        } else if (packet instanceof PacketPlayOutWorldParticles) {
            PacketPlayOutWorldParticles p = (PacketPlayOutWorldParticles)packet;
            try {
                Field particleField = p.getClass().getDeclaredField("a");
                particleField.setAccessible(true);
                Particle particle = (Particle) particleField.get(packet);
                if (particle == Particle.SWEEP_ATTACK || particle == Particle.DAMAGE_INDICATOR)
                    return;
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
        super.sendPacket(packet);
    }
}
 

Thanks in advance
