How to insert other Word files into an open document

Using Document Server plugin:
I want to insert other Word file content into the document I am currently editing, Can it be achieved, and how can it be achieved?

Hello @zazatyty,
Inserting a docx into another docx file is possible via content controls using this method:

The file you want to insert must be available via url:

Thank you for your reply. I will give it a try, and if there are any issues, I will ask again

Attempt to use URL failed, what kind of URL should be passed?

I tried using the same URL as the editor to open the document, and the URL used by the editor can successfully open the document(the document shown in the first picture can be opened normally using this address)

Try to download the file using this URL from the terminal of the server where your Document Server is installed using wget command and attach the screenshot with the output.
