Lock the iPhone by iWatch at necessary cases.

Dear support team,

My name is Hamdan. The new mask update was grateful. I have an idea for emergency situations. So can you make updates that someone can lock his iPhone by iWatch in necessary cases like if i forget my phone is unlock and I’m little bit far from my phone so in this time i have someone near my phone and I don’t want him to check my phone so in this time need to lock my phone by my iWatch like there is a way to lock the iPhone from the iWatch. I hope you the idea.

Thank you
