Add Reaction to Trigger Message Before Responding

[troublescope]

Describe the feature you'd like to request

I would like the bot to add a reaction to a trigger message or command before sending its response. This would enhance user experience by providing immediate feedback that the bot has received the command and is processing it. This feature could be especially useful in busy group chats, where it’s helpful for users to know that the bot is actively responding to their command.

Describe the solution you'd like

When a user sends a trigger command, the bot should react (e.g., with an emoji like 👍 or 😀) to the original message as soon as it’s received.
This reaction should happen before any processing or response output, providing instant acknowledgment.
This could be a simple reaction or an emoji based on message context, and ideally, it would be configurable so users can enable or disable the feature based on preference.
