When I click on Zoho mail to open

When I click on Zoho mail to open

Hello,

Every time I click on the Zoho mail icon in my Chrome browser it opens as if I want to compose a new message. *
Why doesn't it open to my first unread message in my inbox ?
I've looked in settings but can't seem to find a way to get it to open the first unread message in my inbox, can someone
help me resolve this issue ?

Thanks,
Bruce
