Block Guess access from selecting pop-ups or advertisements

Hi, when giving other users guess access to the camera system, they get limited access with no settings access or control BUT

how can we stop or limit guess access from setting up or selecting promos or aosu protect+ plus features or promo’s monthly or annual promo options from advertising pop-ups or from the store ??? how can we stop access to these functions from guess access they should have no control over this.

so the reason I need this currently accessible function stopped is my wife has Parkinson’s which means nerv damage so her hands shake with no control over her actions and already by accident she has selected a few features from advertisements or pop-ups on her screen as a guest that could have cost us money we don’t have so I need to stop this function from happening again either by her or kids accidentally selecting these options that should be blocked under the guest users setting.

what can we do to stop this access that should be limited along with the other settings that are restricted under the guess access settings.

can you add a toggle switch under settings to stop guests from accessing this function or just block this accessibility outright that way they can see the promo’s or advertisements but it’s block for guests…
