How to implement Drag And Drop on grid?

Question

React

I want to make a small toy in react, where it is necessary to drag the cells arranged in the form of a grid onto each other and as a result, when two cells are connected, you get 1 cell, but another one.
I found 2 articles on the learn.javascript.ru site , but everything is there for the mouse, but it is necessary for the phone. I also looked at the react-beautiful-dnd library, but in the examples absolutely everything is tied to lists or boards like Trello. Tell me where to dig or where to look?)
