Check if inventory and hotbar is full

Hey so Im trying to create an advancement that constantly checks if the player has an empty slot or not. There is an advancement trigger that does that, though it also checks if the armor slots and the offhand slot also has an empty slot. That is what i want to exclude. I want to only check if the inventory or hotbar has an empty slot; if yes: then set a score to 1; if no: set a score to 0.
