cacheManager.getMasterPublicKeyInfo(); // ckb-cli using this key by default

// now you can using following methods
cacheManager.getNextReceivingPublicKeyInfo();
cacheManager.getNextChangePublicKeyInfo();

// or collect cells  by CellCollectors
const cellCollector = new CellCollector(cacheManager);
// or with queryOptions
const cellCollector = new CellCollectorWithQueryOptions(
  new CellCollector(cacheManger),
  queryOptions
);

for await (const cell of cellCollector.collect()) {
  console.log(cell);
