Good Afternoon my Electrical Worker Hero's

I have no idea what to purchase to work with our current house. I am an amateur DIY person who knows enough to power down the house before adding a light switch. In theory should be easy :)

In Theory!

I have a what I "think" is called a three way set up for my garage lights. We have one light switch inside our house and another inside the garage. They work great!

What I would like to do is place motion sensor light switch inside the Garage so when someone goes into the garage the light automatically goes on until the person leaves. But if someone turns on the light switch inside the house the light will stay on until they turn off that switch. What type of motion light switch should i purchase? What keywords do i need to look for? Is there anything special that needs to be done to install this type of switch?

Honestly I know this might be a simple one, I appreciate the time you have taken to help me.
