Why you are asked for install unknown applications permission
The intervention of the android operating system to stop the execution/installation of a 3rd-party, unknown APK file is due to the fact that it's an installation package outside play store environment and since it's not been installed or verified by Play Protect, it does not have the approval to pass android OS security checks. However, that's not the end of the world and you can easily execute such process by enabling Install unknown applications permission. Remember, this is safe as long as you know the source of that APK file being genuine, so act responsibly.
