I far as I know for Qliksense cloud user here is the Qlik's response :
Can I use Qlik Sense Business to unlock Qlik Sense Desktop?
No, currently the only option is to authenticate Qlik Sense Desktop against Qlik Sense Enterprise on Windows. We are working to provide authentication via Qlik Cloud Services including Qlik Cloud Business."
there is a post by Josh_Good "Yes we are still planning to enable Qlik Sense Desktop to authenticate against Qlik Cloud Services. We are currently on track to have this included with the June 2020 release for Qlik Sense Enterprise SaaS and Qlik Sense Business."
