wixCrm cannot be imported

Hi, Could you tell me whether if it works for you guys. Either I’m terribly missing something or some hickup with Wix. I get for a standard import a pretty ugly error:

Cannot find module ‘wix-crm-backend’ in ‘public/pages/masterPage.js’

the import is the standard:

import wixCrm from ‘wix-crm-backend’;
