Help Needed: UI Animations for ArchViz Project in Unreal Engine 4.27

Can anyone help me make this UI for an ArchViz app I’m working on in Unreal Engine 4.27? I already made the layout, but I’m having problems with the animations.

The first animation is for the four options below. I want to make the underline slide smoothly between these four options when hovering over any one of them.

The second animation is the scrolling bar in the middle-right of the screen. I want to create it and attach it to the camera sequence, so it becomes part of the background of this main menu. That way, whenever the camera switches to the next scene, the scrolling bar moves one step forward in a loop. this makes me able to go back and forth between scenes, and the scrolling bar should update accordingly.
