How to check if Sphere Collider is fully in other collider | VR-Game

Hello,
I am currently making a VR game and I have set everything up just right.

PROBLEM:
The hands of the player have sphere colliders and I want a script (on each hand induvidualy) to check if the sphere collider is complitly inside a different collider.

WHAT I ALREADY HAVE TRIED:

  • On Trigger enter/exit - as soon as the sphere collider is complitly in the other collider it just “runs” on trigger exit.
  • Raycasts and Sphere Raycasts - when the sphere collider is in the other collider it just doesnt notices the other collider

INFO:
Editor Version: 2021.3.30f1
The other collider is not specific like it can be any collider. And I want to do it with a layer mask…
And I want to make a movement system kinda like Gorilla Tags but I want you to have to grab inside a wall to hold onto it, so also if the collider isnt fully in the object it should also work.

Sorry for my bad english, I am german :wink:
Thanks
