Creating a dynamic WeakAuras 4.0.0 like in this YouTube Video

Hello,

I’m looking to create an aura in WeakAuras 4.0.0 that adjusts its size based on the camera distance, similar to what is shown in this video: https://www.youtube.com/watch?v=16U6jBTMIoU&t=1s.

I’ve read that the Personal Resource Display option might be needed, but it seems to have appeared in a later version.

Is it possible to achieve this effect with WeakAuras 4.0.0 without that option? If so, what scripts or configurations can be used?

Thank you for your help!
