Cannot install 1.0.x with 10.x

@goz, in composer.json, you have to have to set the "minimum-stability": "beta", and you would be able to install(require) 1.0.0-beta5 on Drupal 10.4.x

As pointed on my topic, composer require works, but Drupal module install doesn't

@goz, I am able to install ui_icons, ui_icons_backport and other ui icons module(1.0.0-beta5) on Drupal 10.4.1. Kindly mention the exact
Drupal version/ui_icon version which is not getting installed from your end.
