实时日志 wx.getRealtimeLogManager is not a function?

if (window.wx) {             const logger = wx.getRealtimeLogManager()             console.log("_____ test wxLog",logger);             logger.info({str: 'hello world'}, 'info log', 100, [1, 2, 3])             logger.error({str: 'hello world'}, 'error log', 100, [1, 2, 3])             logger.warn({str: 'hello world'}, 'warn log', 100, [1, 2, 3])         }

请问这个实时日志是不支持小游戏吗？
