How to achieve this tweening effect

So, im trying to do a tween like this one: basically, it tweens to all angles and not just down and right, some games like Tower Defense Simulator have this effect and i would like to know how to do it

By the way, its in portuguese bc im from Portugal

Video of it

You just increase the size of the frame/button/container. If your anchor point is the center (0.5, 0.5) then it will expand in all directions.

Waittt ohhhh it was just me being dumb then, thx!
