How to use the electron-json-storage.remove function in electron-json-storage

exec(pinRmCommand, function(error, stdout, stderr) {
    storage.remove(pinHash, function(error) {
      hashList();
      if (error) throw error;
    });
    if (error !== null) {
      console.log('exec error: ' + error);
    }
  })
}
