Users wants a snippet of code to open a synced Realm with their cloud URL and/or demo apps

I added this from a comment on a Google Doc:

@bigfish24:

After they get access they should probably be presented with the ability to get a code snippet to open a synced Realm with their cloud URL and/or demo apps. The chat demos will likely be partially ready by Dec 1 in a MVP level.

This probably needs to be presented with code snippets for different platforms / languages.
