Hi ,
For multi-step animations, your best bet will likely be to use scene states, where each step of the animation has its own scene state. You can't delay the start of an animation, which makes creating a sequence of animations all in one go difficult or impossible, so scene states let you bypass that by isolating each animation to the scene state.
Once your scene states are set up, you will have three separate animations in three separate scene states, which you can splice together in a video to create a smooth animation.
For more info on working with scene states, you can review the documentation here.
Best,
