[1.18.1] Custom Items and Splash Potions

What is the best way to make a splash potion drop on the ground upon right clicking with a custom item? I overrode use but I'm not quite sure about how to get the splash potion to drop.

public class TitaniumLongswordItem extends SwordItem {

    private static Properties properties = new Item.Properties().tab(CreativeModeTab.TAB_COMBAT);

    public static Item INSTANCE = new TitaniumLongswordItem(Tiers.IRON, 17, 2147483646, properties).setRegistryName(BaseMod.MODID,"titaniumlongsword");
    public TitaniumLongswordItem(Tier tier, int attackDamageIn, float attackSpeedIn, Properties properties) {
        super(tier, attackDamageIn, attackSpeedIn, properties);
    }

    @Override
    public InteractionResultHolder<ItemStack> use(Level level, Player playerIn, InteractionHand handIn){
        ItemStack itemstack = playerIn.getItemInHand(handIn);
        BlockPos location = Utils.getBlockAtCursor(playerIn, 20.0d, true);
        Entity entity = new ThrownPotion(EntityType.POTION);// new MobEffectInstance(MobEffects.HARM);
        //float explosionRadius = 0f;
        if(location != null){
            //Utils.strikeLightning(level, location);
            //Utils.createExplosion(level, location, explosionRadius);
            Utils.spawnEntity(level, entity, location);
        }
        BlockPos blockPos = Utils.getBlockAtCursor(playerIn, 20.0d, true);
        if(blockPos != null){
            playerIn.teleportTo(blockPos.getX(), blockPos.getY()+1, blockPos.getZ());
            playerIn.fallDistance = 2.0F;
            playerIn.addEffect(new MobEffectInstance(MobEffects.DAMAGE_RESISTANCE, 50, 150));
            playerIn.addEffect(new MobEffectInstance(MobEffects.FIRE_RESISTANCE, 400, 2));
            return InteractionResultHolder.pass(itemstack);
        }
        return InteractionResultHolder.pass(itemstack);
    }
}
