How do I test google play service in Construct preview mode?

I want to test google play service in preview otherwise I have to export apk then upload to playstore then wait for approval and after that I can test if its working or not. So how can I test it in construct preview?

I followed official documentation here but at the end it only displayed google login popup I want to test leaderboards and achievements too.

but we can download and play only when app is approved until then app doesn’t available to download

Well there's a sandbox environment specifically for testing these things before you submit it for review or before releasing to production. You download it from a test link. That's on the Google side not Construct, it's part of the process.
