Hi there, and many thanks for the great work !
I would like to set the sessionidle parameter in /etc/onlyoffice/documentserver/ as advised in https://github.com/ONLYOFFICE/onlyoffice-nextcloud/issues/168#issuecomment-683620998 This setting is really important as it determines the time a user session is considered idle and thus the onlyoffice cache is flushed into the nextcloud file. By default, it is never flushed, so if a user is still connected to a document, the modifications performed by any user are only present in this cache and nextcloud file sync does not see them.
As the container is read-only, the default.json config file cannot be modified. Any tip to do that, even at the command line, even if a stop / restart of the docker container is implied would be greatly appreciated, independently of a more long term solution.
