Installing DXO Nik 1 plugins in Affinity Photo for Mac

[Russ 1]

Can anyone point me to a link of a video or text that explains how to install the DXO Nik 1 plugins in Affinity Photo 1.6 for the Mac? I have it installed on one of my computers but need to do it on another and cannot remember how I did it. I had some instructions I found on the web that were very good that I recall, advising to have the plugins folder on the desktop. I usually keep such documentation for future use. But unfortunately I do not appear to have kept a copy. Searching on the web now the only thing I can find are installation instructions for free Google Nik version.
