Add URI Scheme to rcapp:// to bring up SMS Conversation

There needs to be a URI Scheme that brings up the RC app to a specific SMS conversation. Something like: rcapp://sms?number=<phone number>.

RC has implemented various other URI schemes for some functions in RCApp, but not to get to SMS? https://developers.ringcentral.com/guide/basics/uri-schemes

I strongly feel that RC needs to be to expose the complete functionality of the RC app via a complete set of URI schemes. Its a win for everyone.

URI's make for an easy way to more seemlessly integrate RC & its feature set into customer environments. URI's don't require the end user to be a coder. The more heavily RC is integrated into a customer site, the less likely that customer would be to consider other providers. Its a win for everybody.
