What is the minimum chrome version for ionic 4 on Cordova?

I developing a desktop and mobile app using ionic

I need to support XP for desktop app

So for windows XP I decided to use nw.js

But NW.js supports XP upto 0.14.7 that is chrome 50

So my question is, does ionic 4 with cordova support chrome 50 ?

Or else what is the minimum chrome version for Ionic 4 ?
