1. Is this request related to a challenge you're experiencing? Tell me about your story.

I try to use LLM node in workflow, I need LLM to send message to issue owner and get response. But currently the LLM can't use plugin tools, this is inconveniounce.
If the LLM node can use tools like it in chat bot, will reduce the complexity.
