Find my Phone : How to make a sound on my phone when it's on silent

Hi, I have a very genuine life issue. My phone (iPhoneX) is always on silent. When I lose my phone, and when I try to find it using my Fenix 5x watch, through the "Find My Phone" app, phone only vibrates.

I used to have an Apple Watch before. When I try the "find my phone" feature on the Apple Watch, phone will make a sound even though it was on Silent. 

Can I make that happen through my Fenix 5x too please? I tend to lose the phone a lot and can never find using the watch, as phone doesn't make a sound. 

Thanks
