Unable to click on icons in React Native Modal even with zIndex - react-native

Question

I have a problem where the two materialicons / touchables in the view can't be clicked. (refer to the code section with the View and zIndex.
I may just be nesting the views wrongly.
When i add a zIndex, it fixes for IOS, but dosen't work for Android.
When i remove the ZIndex, it fixes for Android but dosen't work for IOS.
When i remove the whole it works on both, but i lose the
ability to do the space-between as i want to put the icons on the
opposite end of the row.
Would love some advice on why this is the case. Thank you.

I took a crash course on flex and solved it using good flex skills then relying on Z-Index
