Set up Zendesk for customer support with WhatsApp, Slack, Teams, Telegram

I'm looking for help setting up Zendesk for customer support with WhatsApp, Slack, and Teams. Out of these messaging platforms, I'd like to manage messages in/out with Zendesk. I have some ideas for a workflow for handling customer support requests, but I'm open to recommendations. The customer support team will consist of 1-5 agents. I need help setting everything up and optimizing the system for smooth customer support operations.
