Video on Archive Page?

I am trying to see what modifications I would need to make to what template in a child theme in order to display the video on the archive page? Or, if this capability is built-in, how to use it.

I am rebuilding a client’s site and I use Sermon Manager on both. On their old site, I build a query with Toolset to add the video to the front end and added custom fields, etc… but I would rather it be more built-in, or easier.

Old: https://libertylifecenter.org/media/sermon-archive/
New: https://beta1.libertylifecenter.org/messages/
