Is your feature request related to a problem? Please describe.

We need to integrate Zendesk into our application to enhance the user support ticket management capabilities. This integration will allow the app to handle user tickets directly using Zendesk's ticketing system via API.

Describe the solution you'd like

1. Integration Scope:
   • Enable the app to retrieve and list Zendesk tickets directly within the system.
2. API Integration:
   • Use Zendesk's REST API to connect the app with Zendesk.
   • Support the following key operations:
     • Fetching ticket details by ID and other common parameters if possible.
     • Listing tickets with filters (status, priority, date range).
     • Adding and retrieving comments/attachments.
3. Documentation:
   • Document the integration process, environment variable setup, and usage examples.
   • Provide examples using Zendesk API.
