How to place a shortcut on the screen of a user's mobile device?

Question

JavaScript

Hello!
There is such an idea: to make a button on the site, by clicking on which, the user installed a shortcut / icon on the start screen of the mobile (android, ios) device for quick access to the site. Because when you click on the icon, the user will simply open the site in the browser.
And I’m also interested in such a moment that the link (for the shortcut) can be set to its own (always on the main page of the site), no matter what page of the site the user is on.
