I am trying to make the ray hit an object from the camera using .setFromCamera. I find the object using this

        this.foundButton = this.main.world.scene.children.find(child => child.name === 'Button')

I noticed it doesn't appear on the first few frames however, after 4-6 frames it does start logging to console. I'm not sure how should I delay it from searching till the entire scene loads or am I doing something else wrong. I'm new to programming so I'm not sure if there is a loop or and if statement I can use to delay this search.
