I need to synchronize my Google contacts with Zoho but I can't find a way. 

On this page:  https://www.zoho.com/crm/help/google-contacts-synchronization.html

is a guide how it should work, however when I follow the steps, 

I get into the settings and all I can see is this:  https://files.slack.com/files-pri/T1A62BHA9-F2B49K4F4/google.png 

There isn't any "Google" button. Could anyone pelase help me? 

Thank you
