Hi @Rishabh Gupta ,

Install app from URL is only for Bitbucket Connect apps.

To install Forge apps simply visit the link. See Start sharing your app, where it states

> When your user visits the link, an installation screen appears, ... . It displays information about your app, including the permissions your app is requesting. From here, your user can choose a site and product to install your app onto.
