Could not find a declaration file for module 'alertifyjs'. implicitly has an 'any' type

Question

I have installed npm install alertifyjs and i am using angullar version 16 and alertify version "alertifyjs": "^1.13.1",

After install all required modules still getting error like

Could not find a declaration file for module 'alertifyjs'. 'c:/Users/lenovo/OneDrive/Desktop/Angular/kanha-app/node_modules/alertifyjs/build/alertify.js' implicitly has an 'any' type. Try npm i --save-dev @types/alertifyjs if it exists or add a new declaration (.d.ts) file containing declare module 'alertifyjs';ts(7016)

I have give the correct path in angular.json as well still getting error,
