Great feature. I do think it could be made a little more discoverable, though, so it is less likely to be overlooked or misunderstood. I know I missed what Ask was intended to do.
Perhaps a tooltip on hover, or a small help/info icon next to Ask, could briefly explain that it opens the AI Bot feature.
Another possibility would be slightly more descriptive button text, such as Ask AI, which might make the purpose clear without requiring any additional interaction.
