how to configure enum in polkadot.js

Following is my substrate code:

pub type ItemId = u8;
#[derive(Encode, Decode, Copy, Clone, PartialEq, Eq, RuntimeDebug)]
pub enum PoolId {
    TX(ItemId),
}

How to configure enum type in the json file? https://polkadot.js.org/apps

This is not working:

{
  "PoolId": {
    "_enum": [
      "TX"
    ]
  },
}
Solution 
  • {
  "PoolId": {
    "_enum": [
      "TX"
    ]
  },
  "TX": "u8"
// or
// "TX": { "_": "u8" }
// or
// "TX": "ItemId",
// "ItemId": "u8"
// or
// "TX": { "_": "ItemId" },
// "ItemId": "u8"
}

    Also here's a real world example:
