What would be the way to debug Play Store then?

Imagine we have ARC++ kiosk session running and kiosk app is not delivered.

How about having a certain cmd line parameter?

This code auto-starts Play Store app on first sign in into ARC++ session for
opt-in UI. This workflow is not needed for ARC Kiosk, but it doesn't prevent
from starting Play Store app to install the app if needed.

+  // mode must be the kiosk app and device is not needed for opt-in.
+  if (!IsOptInVerificationDisabled() && !IsArcKioskMode()) {
     playstore_launcher_.reset(
         new ArcAppLauncher(profile_, kPlayStoreAppId, true));
