How to change positions of icons on Xamarin Shell tab bar

Question

I'm using Shell on a Xamarin Forms app and the icons that I'm using on the TabBar are a little bit too high up

I would like to change their positions to the center but I can't find a way how.
How would I change the positions/alignment of the icons? TabPage xaml
