What is this "Search Email is ZohoCRM" box and how do I get rid of it??!!

I had trouble accessing my Zoho account today and once it got fixed (it required me to "grant data access to Zoho") EVERY EMAIL in gmail has this Zoho box at the bottom asking me to search for their email address in Zoho.

How do I get rid of this stupid box that I don't need and didn't ask for?
