How do I change 'from' addresses in Zoho Mail?

I am trying to change some of the 'From' addresses in Zoho Mail. I found instructions is the Zoho Mail User Guide under Display Name - Outgoing Emails that says

Steps to change Display Name

  1. Login to  https://www.zoho.com/mail 
  2. Select Settings >> Mail >> Send Mail As 
  3. Click the 'Edit' icon across the particular email address under 'Configured From addresses'
  4. In the 'Display Name' text box, provide the preferred Display Name
When do step 1, there is no Settings link to click.  Are there updates instructions somewhere else? How to I do this? I managed to do it a couple years ago, but can't get back into it.
