NSSpellChecker does not return my dictionaries from ~/Library/Spelling

• Node Version: node 12.18.3, npm 6.14.6
• Platform: MacOS

Hello guys, I'm not really sure where can I send my issue with macOS, so sorry if this is not the right place.

Node-gyp builds my native module which depends on native spell checkers. For some reason when I run build with node Javascript, it doesn't return my dictionaries from ~/Library/Spelling ( it returns only installed 'system languages' )
When I created a simple objective c app in Xcode, it shows me all languages include my dictionaries from folder ~/Library/Spelling

Simple code:

#import "spellchecker.h"

#import <Cocoa/Cocoa.h>
#import <dispatch/dispatch.h>

Spellchecker::Spellchecker() {
    NSLog(@"%@",[[NSSpellChecker sharedSpellChecker] availableLanguages]);
}

Spellchecker::~Spellchecker() {}

Please, any idea why my node-gyp build is different from native?

Start with the reported node-gyp native-module build and the Objective-C entry point in spellchecker.h; compare its NSSpellChecker availableLanguages result with the simple Xcode app. Confirm whether the discrepancy is in node-gyp or the macOS execution context, and establish a reproducible result before defining what a fix would require.
