Unable to generate flow and use it in screen

I designed a loader but I am unable to see the flow. The idea is to make a bouncing ball. I created a frame, designed all of them, made their components and combined all as one variant. Then, I just connected them all and animated them. But I do not see the FLOW option anywhere to test the animation. Also, I intend to use it inside a screen and that too isn’t working.

Here is a screenshot for better understanding. Please help me:)

Do you mean this thing?

It shows up then you’re in prototype mode and have a flow starting point. It will automatically create one when you make a connection between frames (not component variants).

If you want to test your animation, place an instance of the component in your frame and click the present button.
