AI functionality on Free Plan

I tried Miro for the first time several months ago and signed up with a free plan. At the time I was able to use the AI to construct and edit frames from the chatbox. When I try to do the same thing now, the AI tells me it can’t access frame construction but not why.

Is this still a functionality of free plans, or was it removed in the last few months? I thought I had 10 tokens per month and have not used Miro in the intervening months.
