Hello everyone.I am trying to implement an application in both android and ios, that will present a floating button overlay in every screen on the device. I have implemented it in the android via floating activity creation, but i cannot do it on the ios. I have seen many examples but they only implement it within their application. I would like to ask if such thing is possible in ios devices and if so how should i approach it.Examples:https://github.com/Flipkart/fk-ios-chat-headshttps://github.com/brutella/chatheadsThank you in advance,Demetris
