How to use the loglevel.getLoggers function in loglevel

function setGlobalLevel(level: any) {
  Object.values(logger.getLoggers()).forEach((lg) => {
    lg.setLevel(level)
  })
}

export function setAll(lvl: loglevel.LogLevelDesc): void {
  Object.keys(loglevel.getLoggers()).map(key => {
    const lg = loglevel.getLogger(key);
    lg.setLevel(lvl as loglevel.LogLevelDesc);
  });
}

loglevel.setAll = (lvl) => {
  Object.keys(loglevel.getLoggers()).map(key => {
    const lg = loglevel.getLogger(key)
    lg.setLevel(lvl)
  })
}
