Effectiveness of HubSpot's Prospecting Agent for Outreach Strategies

Hi guys, Does anyone have experience with HubSpot’s Prospecting Agent? It’s supposed to research and execute personalized outreach strategies for prospects directly within HubSpot’s Smart CRM, helping build a more qualified sales pipeline. Is it actually effective for cold outreach or is it more suited for nurturing warm leads (e.g. marketing campaigns or website visitors)? Would appreciate any thoughts from those who’ve actually used it. Thanks!
