Parameters available:
-p | --platform - Optional. Specific platform, otherwise all platforms would be used for bundling.
-b | --binaries - Required. Folder with binaries (should have folders inside, like android_x64, linux_arm64).
-s | --suffix - Optional. Suffix to add to a zip file.
-t | --target - Optional. Where to copy result zip file.
