Zoho Translator for Zoho Desk not working

Zoho Translator for Zoho Desk not working

We have added the Zoho Translator extensions in our Desk environment, but when trying to use it we do not have the option to select the translation language within the ticket. We have followed the setup process for the extension as outlined in this help article https://help.zoho.com/portal/en/kb/desk/integrations-and-marketplace/agent-productivity/articles/translate-ticket-conversations-with-zoho-translate#InstallingZoho_Translate_Extension

Has anyone had this issue or able to advise to possible causes?
