How to add NSLocalNetworkUsageDescription to info.list file

I want to build my ue4.26 project to iOS. When I package to iOS, some keys are missing in info.plist. For example, I need to add NSLocalNetworkUsageDescription to the plist file. I can’t find the way how to do it when package to iOS on Mac.
Please let me know if you are familiar to this.

Thanks.
