When a Slack interaction occurs\u2014such as a user triggering a vulnerability scan or generating a report through a modal\u2014the workflow intelligently routes the message to the appropriate action:\n\n- **Dynamic Routing**: Uses conditions to determine the nature of the Slack interaction, whether it's a direct command to initiate a scan or a request to generate a report.\n- **Modal Management**: Differentiates actions based on modal titles and `callback_id`s, ensuring that each type of submission is processed according to its context.\n- **Streamlined Responses**: After routing, the workflow promptly handles the necessary responses or actions, including closing modal popups and responding to Slack with appropriate confirmation or data.\n\n**Purpose**: This mechanism ensures that all interactions within Slack are handled quickly and accurately, automating responses and actions in real-time to enhance user experience and workflow efficiency."
