Sometimes search does not find the application you are looking for. Have no fear, there's an alternative way to install apps through aurora.
Open a chrome based browser. (Chromium, Bromite, UnGoogled Chromium, or Vanadium)
Search for the App's Google Play Store page & Click the link
Open with Aurora Store, Voila.
