Packing a roku channel help

Im trying to build roku private channel from scratch. I have made and testing roku private channel with help of SDK however i’m stuck on a one issue which is packaging the channel. I do not own any roku devices. Im just trying to build a channel for users to enjoy for free of cost and would really appreciate it if someone can help me package the channel thanks in advance.

You must have a physical Roku, get one.

Buy an older one on Craigslist if you must, but avoid the “classic” Rokus which are no longer supported.
