Issue with Detox (react native) running on Azure DevOps

I have a few integration tests using Detox for React Native and they work fine using Release configuration on my local machine.

However, when I tried to set up the same configuration on Azure DevOps pipeline, it looks like the tests don't pass.

It looks like the Metro Bundler tries to run on new terminal window, but since it is an Azure Pipeline VM it is gets stuck? Then, the tests don't pass. Since it is a release version, maybe there is a way to block this event? The release version doesn't need the bundler to be running anyway.

My detox command:

detox build --configuration ios.sim.release

My detox configuration:

 "ios.sim.release": {
        "binaryPath": "ios/build/Build/Products/Release-iphonesimulator/raio.app",
        "build": "RN_SRC_EXT=e2e.js xcodebuild -workspace ios/raio.xcworkspace -scheme raio -configuration Release -sdk iphonesimulator -derivedDataPath ios/build",
        "type": "ios.simulator",
        "device": {
          "type": "iPhone 11 Pro"
        }
      }

Additional question: Does anyone know how running this xcodebuild line in the terminal makes the Metro bundler to start? Is there any custom Build Phase added to xcode for react native which triggers it?
