Is there a repeat / replay option for Smart TV?

I'm trying to setup a playlist to stream to one of our TV's in my office using video's that we've made. I've setup my computer as a "Server" with all of our video's, and created a playlist. Alternatively I have downloaded the Plex app on our Samsung 75" Smart TV and it see's my "Server" without issue, and the video's play back perfectly.
I'd like to play these video's constantly during a client meeting we are having, but there doesn't seem to be an option where I can loop the playlist. Is there something I'm missing? If so I would greatly appreciate any guidance anyone can offer!
