How to Enable multi-language in SAP FIORI Launchpad

Hi Experts,

Currently I can see only two language(English and German) on SAP Launchpad Login page.

Through the SAP standard document I came to know that we have to redefine below property :

# Application supported languages

application_languages=EN,FR,DE

But I am not able to find exactly where to make the changes to enable Chinese language.

Can anyone please help on this.

Thanks and Regards,

Puneet Jain
