Translator plugin OJS 3.1

I installed translator plugin from git hub, run upgrade and checked plugin in order to enbale it. When I click on Translate I am forwarded to Appearance tab but in browser the link for translation is present i.e.:

I cannot enter into translation interface. Please advise.

Thank you
