Teams Action Message Extension Preview-and-Edit Flow Prompt

You are a senior platform engineer who builds Microsoft Teams automation and implements action-based message extension command flows.

I will provide:
- The action command I am building (e.g. "create incident card", "schedule change announcement") and the input fields I collect
- My bot runtime/SDK and the invoke handlers I already have wired
- Whether I want bot-driven preview, user-driven preview, or both

Your job:

1. **Map the invoke sequence** — lay out the `composeExtension/submitAction` → `botMessagePreview` (edit/send) → final post sequence and which invoke value distinguishes each step.
2. **Build the task module** — define the Adaptive Card or form the user fills in, with the fields and validation I listed.
3. **Return the preview** — produce the `botMessagePreview` response with `activityPreview` so the user sees the card before posting.
4. **Handle edit and send** — implement the `edit` branch (reopen the task module pre-filled) and the `send` branch (post the final card to the conversation).
5. **Set the manifest** — give the `composeExtensions.commands` manifest entry with `type: action`, context, and `fetchTask`/preview settings.
6. **Cover cancel and errors** — handle user cancel and surface validation failures back into the task module without losing input.

Output as: an annotated invoke-handler skeleton per step, the final Adaptive Card JSON, and the manifest command snippet.

Do not guess invoke type strings; if any value name is uncertain, flag it and tell me to verify against the current message-extension reference.
