How to control BinancePortfolioMarginGetMaxWithdraw

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "BinancePortfolioMarginGetMaxWithdraw": {}
  }
}

BinancePortfolioMarginGetMaxWithdraw is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
