Welcome to the Roku Community, @JKE7!
We appreciate you stopping by for support. We'd be happy to help you install the Peacock TV app on your Home screen.
You may install it directly on your Roku Express by navigating to your Home screen. Scroll and select Store/Streaming Store > Select Channels > If the app is free, select Add channel; if the app requires a subscription, select OK to start a free trial or purchase a subscription.
The app will be added to the bottom of the list of apps on the home screen. If you prefer, the app can be moved higher up the list.
Here's the support article for reference: How to add apps to your Roku streaming device
Feel free to respond if you need further clarification and assistance. Hope this helps!
Best regards,
Carly
