Have a way to make an object auto-resize??

Hi, I'm coming from Adobe After Effects, and there is a way to make an object resize automatically, for example, in a mailbox, the text automatically determines the size of the shape, using an expression in the object that will resize ( source.RectAtTime ) if it's confuse, please search that expression on google, and watch the first video, because i'm not allowed to post url .

My question is: Is there a way to do this in Fusion?

I'm using DaVinci Resolve 15.2.

Thank you.
