I am developing apps using NWJS framework, which access devices on the local network. I am doing this on Sequoia on Macos (Desktop). I have developed other apps using NWJS before, but on earlier versions of Macos.
My issue is, I am unable to give my app permission to app to access devices on local network on one of the apps.
Some background:
Other apps which I have used which access devices on the local network, on first-time launching, have given a prompt asking me if I want to allow or deny access to local device for the app.
However, on first-time launching (and many others after that), It simply says the device cannot be reached, and I never get a prompt asking me if I want to allow or deny access to local device for my app.
In its barebones proof-of-concept stage of my app, I have an iframe who's src attribute is the IP address of a device known on the network with that address. I have tried the protocol https://192.168.1.99 and http://192.168.1.99 in the src attribute. This protocol works in another app I have built where upon first-time launch, I was able to get a prompt and give it the needed permission.
If I check in System Settings > Privacy and Security > Network, the app doesn't appear where I can toggle a setting. I also am unable to explicitly add my app to the list.

This worked for one app, but not another:
In researching this issue, it was recommended that I add the following keys in info.plist:
com.apple.developer.networking.multicast - boolean true NSLocalNetworkUsageDescription - string description NSNearbyInteractionUsageDescription - string description
This worked for one of my apps, but not another, which has a nearly identical structure. In fact, other than CFBundleIdentifier, CFBundleDisplayName and CFBundleName, info.plist is identical.
Why did this work one time, and how can I get my app to prompt for permission for local network access?
