You are helping me build the following AI agent workflow.

## Goal
Two-Way WhatsApp To Telegram Support Sync: Bridges WhatsApp customers to Telegram support agents by creating dedicated topic threads for each conversation.

## Specification
- What it does: You instantly organize every WhatsApp customer message into a dedicated Telegram thread so your support team manages thousands of chats efficiently. This bidirectional sync keeps you connected to customers on both platforms while eliminating the need for custom software development.
- Trigger: Triggered by an event (Event · on new message)
- Autonomy: Fully hands-off
- Expected setup effort: a few focused days
- Tools/services involved:
  - n8n: Workflow orchestration and automation logic
  - WhatsApp Business Cloud API: Receiving and sending customer messages
  - Telegram Bot API: Managing support agent threads in supergroups
  - Supabase: Storing customer to topic mapping data

## Known pitfalls, handle each one explicitly in your implementation
1. Telegram topics require a forum group type so ensure your target Telegram chat is configured as a forum before attempting to create threads.
2. Supabase row-level security can block reads if not configured correctly so verify the service key has full access to the mapping table.

## Reference implementation
https://n8n.io/workflows/8350 (workflow template)
Fetch and inspect this before building. If it matches my stack, adapt it;
if not, rebuild the pattern with my tools.

## Process requirements
1. Before building: ask me which of the listed tools I actually use and
   what my platform is (n8n / Make / code / other). Do not assume.
2. Adapt the pattern to my answers; do not force the reference stack.
3. Address every pitfall above; tell me how you handled each.
4. Provide a test plan I can run before letting this touch real data.
5. Ask before any step that sends messages, modifies data, or spends money.
