How do I launch an external application from the browser like Telegram url links?

I am trying to recreate the following application launch with telegram when one visits the telegram user profile page. Example: https://t.me/username1

When the page is loaded, it gives an alert box to open the telegram app. How do I recreate this as a URL link on a webpage? Also how are they doing this on page load and where is it in the source code so I can see it?

Use tg just like you use mailto

tg://resolve?domain=username1


<a href="tg://resolve?domain=username1">Message me!</a>
To launch it page load, just use the standard DOMContentLoaded and redirect the browser; 
document.addEventListener("DOMContentLoaded", function(event) { 
  window.location.href = "tg://resolve?domain=username1";
});

I've searched quite some time to find any documentation, there is one reddit post from 1 year ago, but they only shared the 'source file'.
