HomeKit Open Garage Door keeps asking for additional confirmation

I can’t say for certain but I believe it’s a security feature to prevent an unauthorized person from gaining access to your home. For example you may have another device in the home that could hear the Siri command or in the case of someone you once shared the home with that you don’t want using their device to get inside. As well as Siri not understanding a Siri request to turn on lights or whatever when inside the home and it unbeknownst to you opens the garage by mistake. Some wanted the extra authentication due to these or other reasons.

Or does it work better if you say hey siri open the garage, without holding the side button to invoke Siri, Siri responds by voice are you sure and you can say yes?
