Mendeley on Endless can't login

It seems that Mendeley does not support version 6 of Libre Office due to plugin issues. Any suggestion of how I could resolve this problem, as I already have hundreds of citations and I am not able to generate the references (not even copying and paste as formatted citation)…
Thank you all.
