How to load notification alert on top right corner without click of button in bootstrap ?

Bootstrap Toast component provides an easy way to mimic the functionality of push notifications. Bootstrap Toast is like an alert box that can be displayed to the user whenever an event occurs. This component has been built with CSS flexbox which makes it easy to position and align.
It is not necessary to show the toast on a button click. It can be shown for any type of event that occurs in the browser. Let’s see an example.

Example: Creating Bootstrap Notification/Toast. In this example we will show a push notification when the user scrolls the <div> in the page. To create a bootstrap toast we need to use the toast class on a division and add two divisions inside it with classes toast-header and toast-body. We will show the notification using jquery.
