How to create this effect? (GIF)

I’ve jumped into UMG and the water is fantastic! Loving the possibilities.

However, I’m confused how to make the swing effect, still. I can certain move a widget or change the alpha of an image through the UMG animation but I don’t see how I could have it rotate or swing according to a timeline or curve of some sort. What am I missing?

Is the only way to do by rotating the whole widget through another blueprint? What if, just like in the example, I only want part of the text to swing? In that case I wouldn’t want to rotate the entire widget according to a timeline, but just one part of it.

Thanks!
