XnView Software

I am using: XnView MP MacOSX Version 0.90 64bits (Mar 4 2018)

MacOS High Sierra version 10.13.5

So I have the latest version of XnViewMP and MacOS.

I still don't get XnViewMP as an option in the "open with" dialog when trying to open a .gif file.

When I right click on a .gif file, then select "Open With", XnViewMP is not listed as one of the applications that can open the file.
Is there some way that I can associate XnViewMP with .gif files? I thought it would already do this.
Thank you
