FileExtension supported by onlyoffice

[NI3]

I have deployed Integration Edition of OnlyOffice server on Windows. Now I came to know that few file formats such as docm, .png, .jpg etc are not supported while few are supported by onlyoffice server for editing. So I wanted to know the configuration on server where the list of supported and unsupported files can be found?
Where does the server exactly maintain the lists of supported and unsupported file extensions?
