This initiates the workflow by passing the email content forward for processing.\n\n### \\* The next node, named **\"Summarize Email and sent to Slack\"**, acts as a processing bridge. It takes the raw Gmail email body and sends it to the connected AI model for summarization before forwarding the processed result downstream.\n\n### \\* The **Google Gemini** node named **\"Google Gemini To Summarize Email\"** uses the Gemini LLM model to generate a concise summary of the email. This ensures only the key points are extracted instead of sending the entire raw email.\n\n### \\* Finally, the **Slack** node named **\"Post Summary to Slack User\"** posts the summarized email content into a designated Slack channel. This allows the support team to stay updated with short, actionable summaries instead of sifting through full emails."
