Webmin cannot be installed as an APP from the login screen

SYSTEM INFORMATION
OS type and version	Ubuntu Linux 22.04.3

Background

Through chrome on an android phone you can install websites as apps on your phone (very handy) if it has a proper manifest file and an appropriate declaration in the html.

The Issue

In authentic-theme/webmin you cannot add webmin as an app from the login screen which is the first place you would land before adding webmin as an app, but you can add webmin as an app once you have logged in.

Proposed Solution

Allow users to add Webmin as an APP at the login screen by doing the following

• Add the html code into the login screen

  <link data-link-ref crossorigin="use-credentials" rel="manifest" href="/manifest-webmin.json">

• Make the /manifest-webmin.json available before login.

Why

If I could not add a website as an APP before I logged in, I would not expect it to allow you to add it as an APP after you login.

This is a very useful feature and is becoming more popular.

Hello,

Thanks for the heads up! Although, this is already possible, e.g.:

However, you won't see this button unless you have legit (not self-signed) SSL certificate installed for your domain.

:smile: the issue is that it cannot be done from the login screen, the code is missing. People (like me) might not figure this out. Normally this feature is not behind a credential wall, login comes after installing the app.

Thanks for the heads up on requiring a real SSL.

Alright, thanks! Fixed on the latest commit!
