Looping LinkedIn Video- Premiere Pro

Hi there! 

I am struggling to get my companies LinkedIn video to auto loop. It is saved as an MP4, about 30 seconds long. I was directed to a LinkedIn online class which had been little to no help. It was showing how to add HTML to embedded videos that have been saved as HTML documents.  Because I am trying to upload a native video directly to linkedin, I have not had much luck on figuring out how to apply HTML to my videos. I am not sure if I am on the right track or not. 

So my question is, is there an explanation on how to do this without applying HTML to a video, and if I must apply HTML to my video, how do I go about saving out my video that can be edited in an HTML editor? (I have used Visual Studio Code). And then saved in a format that I can post to LinkedIN. 

Any ideas??
