Kami Extension?

Hi. My daughter is in 2nd grade and her teacher wants us to use Kami. The directions tell me i need to go to kami.app/extension and click add to chrome but there is no add to chrome button. I also get an alert that says we are sorry but you do not have access to chrome web store. Please contact your organization admin for access. Anyone ever have trouble like this?
