Question How to translate "Only community members can participate in this forum. You must register or log in to contribute"

Hello, Im using the newest version of kunena forum.
I set a configuration that only registered users can access my forum.
When someone who is not logged in/registered goes on forum, this message displayes: Only community members can participate in this forum. You must register or log in to contribute .
I want to change this sentence - translate it into my language.
Can you explain me how to find it ?
I chechked every single kunena language file and cant find it.
I even added this line in com_kunena/language/en-gb/en-GB.com_kunena.ini :
COM_KUNENA_LOGIN_FORUM="added sentence on my language here"

but doesnt work.
I took a notice that in some kunena 1.6 version i have many lines in language file that i dont have in this newest verison.
Can you exactly tell me where to find this and edit?

Go to "administrator/language/your language folder/xx-XX.com_kunena.libraries.ini" and change the text.

I went inside /public_html/administrator/language/en-GB/ but i dont have that file...
I uploaded the screenshoot...
I dont know what to do ? Cant beleive i cant find this anywhere...

I thought that you have a different language? You must go in the folder of your language. Have you installed the language package?
