Really like the idea!<p>Im trying it out right now and the Android app told me to use an identifier that starts with a &#x27;9&#x27;. I typed `notify -r &lt;my_identifier&gt;`. When I try running `notify` however, it gives me this:<p>[notify] Encountered an error: ParseError {
  code: 141,
  message: &#x27;Error 112: Channel name must start with a letter: &lt;my_identifier&gt;&#x27; }
