Could not find a declaration file for module 'react-tree-graph'

Question

I am trying to create tree visualization to my react project. When I added a package 'react-tree-graph' and import Tree module from it:

import Tree from 'react-tree-graph'

it shows me this error:

Could not find a declaration file for module 'react-tree-graph'. 'd:/Downloads/CureAssure/F22-011-R-CureAssure/node_modules/react-tree-graph/dist/index.js' implicitly has an 'any' type. Try npm i --save-dev @types/react-tree-graph if it exists or add a new declaration (.d.ts) file containing declare module 'react-tree-graph';

I added the package using

yarn add react-tree-graph

Because I am using Yarn Package Manager.

I thought it might solved by using, npm, So I tried

npm install react-tree-graph --save

But the error remains same.

I visited the question Typescript react - Could not find a declaration file for module ''react-materialize'. 'path/to/module-name.js' implicitly has an any type, and came to know that the error maybe due to .d.ts file, but I don't know why it is not in the folder.

In node_modules, there exists a folder react-tree-graph with these files:
