Best Practices for Integrating Search Knowledge Base in Agent Steps

Hi there, I just wanted to know what would be best practice when adding Search Knowledge Base (KB) as a skill in an Agent Step. I've been trying to make it work (including initialising the KB separately), but nothing has worked. Mind you, I am aware of incorporating the KB before or after the Agent Step (e.g. via conditions) and even calling other agents (via Send Message), but I want to avoid that since I want the agent to use the KB directly as a skill. Could you please help me out here! haha I'm losing my mind on how to make it work for this use case 🤯
