Smart animate not showing

I recently discovered the amazing smart animate option on Figma on YouTube.
I went to my Figma to try it out but that Animation option doesn’t appear on my prototype.
I’m attaching a print of what I see. Can any1 help me?

Smart animate looks for matching layers, recognizes differences, and animates layers between frames in a prototype.

Instead of this you trying to animate inside single frame.
