How can I help translate Akaunting to Khmer?

Hi, the software is awesome.
Sorry, If i ask at the wrong place, but I'd like to help to translate this into my local language (Cambodia - Khmer).
I checked https://crowdin.com/project/akaunting, but there is no way I could add/request for the new language.
Looking forward to hearing from you.
