Due to some complex reasons, using info.plist would require us to modify a lot of logic. Therefore, we expect NSApplicationActivationPolicyAccessory to work as described in the documentation "This corresponds to value of the LSUIElement key in the application’s Info.plist being 1.", rather than displaying the icon in some scenarios.

1.Our architecture dictates that we must launch the application using a parent-child process. 2."If your app employs a child process created with either the posix_spawn function or the NSTask class, you can configure the child process to inherit the sandbox of its parent. ".We have correctly inherited the sandbox according to the documentation, but the User Selected File Read/Write permission is missing. We expect the NSSavePanel work fine within the sandboxed child process.
