I've searched the web up and down, but couldn't find a viable solution for your inquiry. If I search for Quadrant, it appears on its official website, but if I tie the two apps together, nothing comes up which could also mean that compatibility doesn't actually exist between them or they haven't been released yet.
The only place where I found Quadrant is on the following link pasted here. You can contact the official developers to ask them about the possibility of integrating Quadrant with KaiOS.
