Prototype: loop one animation and play another once on the same page

I want a spinner that loops forever and a checkmark that plays once, both on the same frame. When I set the frame's animation to loop, both loop. Possible?

Put each one in its own component with its own interaction. Component-level animations run independently from the frame: give the spinner an After delay → Loop interaction, and the checkmark a single After delay → Change to with no loop.

That works. Didn't realise components could hold their own interactions.
