I took me doing a Google search to find the original Instagram PR release that had instructions on where even to find Reels. But once you are in any Reel it acts just like TikTok, you swipe up for a never-ending feed of content.
So in a sense, any Reel is a portal into "a separate section dedicated to Reels content".
