"run_command" doesn't work in json

Summary: I'm trying to add an item in Minecraft Education, but it's not working as intended.

Details: The addition of the item is successful, and the texture is correctly applied. However, when the item is used, the associated event does not trigger.

JSON I created:

{
  "format_version": "1.20.13",
  "minecraft:item": {
    "description": {
      "identifier": "edu:example",
      "category": "items"
    },
    "components": {
      "minecraft:icon": {
        "texture": "example"
      },
      "minecraft:display_name": {
        "value": "item.example"
      },
      "minecraft:on_use": {
        "on_use": {
          "event": "example_event",
          "target": "self"
        }
      }
    },
    "events": {
      "example_event": {
        "swing":{},
        "run_command": {
          "command": [ "say hi" ]
        }
      }
    }
  }
}
