sendinblue integration option not showing

Hi
https://contactform7.com/sendinblue-integration/
I have checked this but i can’t find out that tab setting for entering APi key/ there is no option is showing for sendinblue integration as per given setup link.

Then open a new browser tab and log in to your WordPress dashboard. Navigate to Contact > Integration menu page and click Setup integration in the Sendinblue box
This is not available
