Allow creating manual gates on slack conversations

We’re exploring whether our slack bot powered by Moveworks can show a notice before it posts any suggested documentation or solution in the IT helpdesk channel. Our ideal flow is:

1. User asks a question.
2. Bot immediately sends a brief notice (we’d supply the copy and any links).
3. The notice includes a button or emoji‑reaction prompt. Only when the employee clicks/reacts does the bot continue its usual response flow.

Nice to haves:

• A simple toggle to enable/disable the gate.
• The ability for us to edit the notice copy without code changes.

Reason: 

We plan to use this during service alerts or outage scenarios. When users report the same issue as everyone else, we turn on the gate and let them know we’re already addressing the outage. If their issue matches the outage, they can wait until it’s fixed; otherwise, they can click the button to proceed with the usual support process.
