inviteUserBySms
Creates an SMS invitation to register an account on Rainbow.
This API generates an invitation URL for the specified phone number. It does not send an SMS message directly. Instead, the invitation URL will be available in the Invitation.invitationUrl property, and it is up to the developer to send an SMS containing this invitation link to the provided phone number.
The developer must manually send the invitation via SMS, for example, by using Android's Intent.ACTION_SENDTO.
Return
A RainbowResult containing the Invitation on success. If the operation fails, the RainbowResult will contain error details.
Parameters
phoneNumber
The phone number of the contact to invite, in a valid format.
