Sync Zoho CRM and RingCentral SMS

We want to send SMS through Zoho CRM leads and deals and have a complete history of all texts for each deal stored and viewable on each lead/deal landing page. We have RingCentral already synced for calls and it seems to work well. Now we want to add this SMS component.

I would prefer to hire someone who has already made this and hope they can send some screenshots of their UI.
