title: Does REQUEST_INSTALL_PACKAGES permission lead to "Google Play Protect warning"?
body: <p>I have built 5 app with different sign key and they are not on googleplay market.
  And user downloads and installs my apps from little banner ad click ,which I put in my apps(Internal downloader and then install app AND NOT market link!).
  I use "REQUEST_INSTALL_PACKAGES" to get install permission and android targetsdk is 28 .Is this permission dangerous to use? And would "googleplay protect" detects it as a dangerous app and show warning protection dialog when user installs it?
  Any help will be appreciated.</p>
