Emergency Call Disclaimer - Hebrew support

When login with Webex user I can see the default Emergency Call Disclaimer in English. When the OS set to Hebrew (Desktop, Android or Tablet) the default Emergency Call Disclaimer also change to a Hebrew message (translated). If I try to change the default Emergency Call Disclaimer message under the Branding template (Emergency Call Disclaimer) tab I have to choose language (English, Arabic and etc.). 1. there is no Hebrew under this menu. 2. If I choose the English (default) option and put the edited message (in English) this message doesn't translated and it's the only message that shown no matter if the OS set to Hebrew. 3. How can I set also a message in Hebrew?
