You can configure the hostname of capacitor apps

"server": {
    // You can configure the local hostname, but it's recommended to keep localhost
    // as it allows to run web APIs that require a secure context such as
    // navigator.geolocation and MediaDevices.getUserMedia.
    "hostname": "unique-app",
  }

and then restrict the the API keys to capacitor://unique-app
