The minecraft behavior  "minecraft:behavior.go_home" won't work if my entity is more than 16 blocks away from the point where it's been spawned. The entity doesn't move. I can make it reach its spawn point by pushing it within the 16 blocks radius. 

Is there a way to change the distance my entity will be searching for its home?

I didn't find any parameter in the documentation.

EDIT : solved it with the component 

  "minecraft:follow_range": { "value": 1024 }
