AppleTV OTT app not showing "Play" button on the build

Question

I'm very new to X Code.. but I'm having trouble figuring out why the "play" button is not showing up on the screen (over the top of a background image) after a successful build of the app in ContentView. Ultimately, I'd like to position the button to a specific area on the screen and have the button launch a video that is hosted on Cloudflare. But, at the moment, I cannot seem to get the button to show up on screen. I get the background to show up after a successful build.. but nothing else. I've tried to use storyboard to drag and drop a button but even that fails to show up. I'm so new to this that I'm getting easily stalled.

                // How the button looks like
                Text("PLAY")
