how to add multiple entrances in config file?

[peow]

im trying to configurate the mod but i don't understand something, i want to put 2 items in this list:

// Codes for which repair items to use for which Ruined Items Ashes (e.g. 'copper_mod:copper_sword/minecraft:copper_ingot;')
"ruinedItemsAshesRepairItems": "",

when i try this:

// Codes for which repair items to use for which Ruined Items Ashes (e.g. 'copper_mod:copper_sword/minecraft:copper_ingot;')
"ruinedItemsAshesRepairItems": "sculkhornid:sculkhorn_sonicboom/minecraft:sculk_shrieker;",

its works, but when i try to put 2 items:

// Codes for which repair items to use for which Ruined Items Ashes (e.g. 'copper_mod:copper_sword/minecraft:copper_ingot;')
"ruinedItemsAshesRepairItems": "sculkhornid:sculkhorn_sonicboom/minecraft:sculk_shrieker;", "sculkhornid:sculkhorn/minecraft:sculk_shrieker;",

it doesnt work, i dont know how to type properly the code
