Healing specific amount of hearts

[CU_Man]

im very new to skripting but im trying to make a skript for soup pvp that makes it so when a player right clicks mushroom stew the skript immediately heals 4 hearts and deletes the held item. Here is my skript

on right click:
    event-player's tool's name = "Mushroom Stew"
    heal %player% [by %4% [heart[s]]]
    send "&a&lThe Mushroom Stew magically healed 4 hearts."
    remove item named "Mushroom Stew" from the player

the heal line doesnt work and i would like to replace the line remove item from players inventory with a line that only takes the item from their hand. then after i want to have aline that adds a bowl in the slot where the soup was. please help

  if player is holding mushroom stew
  heal player by 10 hearts
#Change 10 by the heal u want
