Web Push how can i use without HTTPS?

https://wordpress.org/plugins/web-push/

There's a note in the plugin's description page:

N.B.: This plugin requires your website to be served via HTTPS. Indeed, for security reasons, browsers enforce the HTTPS policy for the Push API and for Service Workers.

It isn't possible to use the Push API without HTTPS. It is a limitation of all browsers.
