Mendeley Desktop remove references field code

Hi everyone! I am preparing a paper, I haved used Mendeley as manager reference program and before submitting it I need to convert to plain text. It is supposed it is possible with an “export as” button in the tool bar but I don’t have this button, is something missing in my toolbar? I have installed the plug-in from Mendeley to libreoffice.

You really nee to contact them. We have no idea how their plugin works.
