How can I change items alignment of a tabbar in React Navigation 5?

Question

So, it seems that default alignment is

alignItems: "space-around"

But I need to change this. I tried to add a style for a tabbar just by passing style for a Tab.Navigator like this:

style={{
    alignItems: "flex-start",
}}

Or like this:

tabBarOptions={{
   style: {
       alignItems: "flex-start",
   },
}}

and this also didn't work. How can I do so?
