NC18+Documentserver+onlyoffice - how to configure?

Dear all,
I successfully installed NC-HUB what results in a working onlyoffice integration which I really like ! surfing around the documentserver_community_edition help pages made me wanting to integrate additional apps like CRM (https://www.onlyoffice.com/de/crm.aspx).
Unfortunately I cannot find and starting point where to configure the documentserver and additional modules & apps. Is this maybe a feature we can only use if installed the documentserver outside of NC-HUB ?
greets, Felix

ok, got answer from onlyoffice support: I need the paid “integration server edition” to use that :frowning:
