Weak Aura 5.20.1 - Display the "direction" of my focus

[drifting bison]

Hello everyone,

I would like to create an aura that allows me to display the "direction" of my focus on version 5.20.1 of weak aura.

I would like, if possible, an arrow to indicate the current direction of my focus.

Could someone help me finalize this, please?

Thank you for your help and have a nice day.

Actually i have this :

I don't think it's possible to get the direction of a unit.
