How to export gene names of contigs?

I assembled my metatranscriptomics reads into contigs. I did annotation for the contigs following the Diamond+Megan long reads pipeline. I was wondering if it is possible to get gene names or protein names for the contigs from Megan.

Please take a look at the menu item

File->Export-> Annotations in GFF Format…

This should report genes along a contig in GFF format.
