How to create a type for a react component with ref support?

Question

React

I have created a small demo here .

I have a basic "Button" component (in "src/components").
"Button.type.ts" contains type definitions through which communication with the rest of the application will take place.
"Button.component.tsx" implements this type.

But what to do when it becomes necessary to define support for ref-throwing in a component, how then to define this type?
