This code implements a spawn shop system in a game where players can receive items based on their selection. The items are defined in a rewardMap and assigned to different reward groups (e.g., Flaming Sword, Mystic Wand, etc.). When a player enters the game, the system checks if they have already received a reward and displays an HTML menu based on their status. If the player hasn't received a reward, they can choose an item from the menu and receive it. The player's status is updated in the database to reflect the reward.


I need assistance understanding how to apply the correct bypass line in the HTML file to trigger the handleItemSelection method from the ModSpawnShop class. The action should pass the correct selection value (1, 2, 3, etc.) depending on which item the player selects. Could you help me understand how to properly create the bypass for this?
