Write Permissions Error While Storing Password in System Keychain Using Authorization Plugin

I'm developing an authorization plugin for macOS and encountering a problem while trying to store a password in the system keychain (file-based keychain). The error message I'm receiving is:

Failed to add password: Write permissions error.
Operation status: -61

Here’s the code snippet I’m using:

import Foundation
import Security

@objc class KeychainHelper: NSObject {
    
    @objc static func systemKeychain() -> SecKeychain? {
        var searchListQ: CFArray? = nil
        let err = SecKeychainCopyDomainSearchList(.system, &searchListQ)
        guard err == errSecSuccess else {
            return nil
        }
        let searchList = searchListQ! as! [SecKeychain]
        return searchList.first
    }

    @objc static func storePasswordInSpecificKeychain(service: String, account: String, password: String) -> OSStatus {
        guard let systemKeychainRef = systemKeychain() else {
                print("Error: Could not get a reference to the system keychain.")
                return errSecNoSuchKeychain
            }
        
        guard let passwordData = password.data(using: .utf8) else {
            print("Failed to convert password to data.")
            return errSecParam
        }
        
        let query: [String: Any] = [
            kSecClass as String: kSecClassGenericPassword,
            kSecAttrService as String: service,
            kSecAttrAccount as String: account,
            kSecValueData as String: passwordData,
            kSecUseKeychain as String: systemKeychainRef // Specify the System Keychain
        ]
        
        let status = SecItemAdd(query as CFDictionary, nil)
        
        if status == errSecSuccess {
            print("Password successfully added to the System Keychain.")
        } else if status == errSecDuplicateItem {
            print("Item already exists. Consider updating it instead.")
        } else {
            print("Failed to add password: \(SecCopyErrorMessageString(status, nil) ?? "Unknown error" as CFString)")
        }
        
        return status
    }
}

I am callling storePasswordInSpecificKeychain through the objective-c code. I also used privileged in the authorizationDb (system.login.console). Are there specific permissions that need to be granted for an authorization plugin to modify the system keychain?
