Password Reset URL -> Deeplink URL Scheme Blocked

My realm app supports deep links in the format appName://path?param=value. In testing I can send a link to the password-reset path with the reset token and it works fine.

However when I go to Mongo to configure Password Reset via email and set the Password Reset URL field it is forcing me to use http:// or https:// as the prefix. Is there any way I can make this work without requiring a server to forward the http:// url to the deeplink appName:// ? Or am I going about this the wrong way entirely.
