Writer - want filename in footer

In Calc, I can include the file name in the footer.

I would like to do that in Writer, but do not see how.

Insert → Field → More Fields → Document tab → pick “File name” and the format you want (full file name, without extension, path, path + file name)

Thanks for your quick reply!
When I select “Insert”, there is no “Field” choice available.
Using Version: 6.3.4.2 (x64)

Found it. While there is not a “Field” choice under the “Insert” tab, there is an Icon on the tool bar.
When I hovered the cursor over each Icon, one shows “Insert Field”, whereupon instructions
provided by RGB-es worked.

This is what I see: (Version 6.3.5.2 (x64) )
