How can I get current localization id number the game is using?

Hello, I’m using Unity Localization Package(version 1.4.3). And I want to get an ID number of localization, whicm my game is using by the moment.

I’ve seen this solution on unity forum:

But there The Questioner gets string Locale Identifier, but not a number, that I need.
I know, that I can set a locale by this code:

LocalizationSettings.SelectedLocale = LocalizationSettings.AvailableLocales.Locales[localeID];

But I do not know how to get that value or maybe I can’t get that value at all.

So, I will be very greateful if someone answer my question.
