To add the "Shortcuts" star button please apply adminimal_theme-add_to_shortcuts-3127508-5.patch in the "adminimal_theme.settings.yml" config file. Working fine. Please check the below image:

After "adminimal_theme-add_to_shortcuts-3127508-5.patch"

But the star icon is not visible properly. So I have applied the second patch adminimal_theme-add_to_shortcuts-3127508-8.patch for the CSS change and It's working fine. Please check the below images:

Before "adminimal_theme-add_to_shortcuts-3127508-8.patch"

After "adminimal_theme-add_to_shortcuts-3127508-8.patch"

Both the patch works fine.
