I have an issue with the api futuresLeverageBracket using TypeScript.
as the document states, the symbol is optional (https://www.npmjs.com/package/binance-api-node#futuresleveragebracket), but futures.d.ts define that it is mandatory
futuresLeverageBracket(payload: { symbol: string }): Promise<Array<{ symbol: string; brackets: Array<{ bracket: number; initialLeverage: number; notionalCap: number; notionalFloor: number; maintMarginRatio: number; cum: number; }>; }>>;
