I can't show you directly, as fedia.io requires login to access the platform (scraper protection), but I was able to open the channel by searching for their handle, the page showed up videos (also recent ones) and the video-posts had comments. The page show the channel-logo and every post had the thumbnail of the video.
One click on the title when you have to post open, and it will open the original page in a new tab, which then can play the video. Even better: Mbin automatically inserts the embedded viewer for the posted video, so you don't even have to leave fedia.

So please don't draw conclusions from Lemmy to all fedi projects.
