Trying to set up my new device but do not have an existing doorbell but I do have a Echo Show 5 I could use it with.

I also don't have an existing chime. The doorbell works fine, ringing the phone when pressed as well as recording videos. I can't speak for the Echo but you generally don't need that other than as part of a connected home.
