LibreOffice Online license clarification

Hi,

Is it allowed to use LibreOffice Online (CODE) as a WOPI client inside a web app (as iframe) to read from a WOPI host, when both web app and WOPI host are closed source softwares? Does it break any license?

It is not a question for the community support site. You better send mail to legal@documentfoundation.org to have some advise.
