Nocolliding player with a prop

As in title, I want to nocollide player with a prop when it is being picked up.
I searched forum and was thinking of lua I can take a look into but found nothing.
I need no-colliding part, not the pickup.

Check if one entity is the player holding the other entity.

You should do this hook both clientside and serverside to prevent prediction errors.
