alch_{ $optionsPageID }_icon

Dynamic filter alch_{ $optionsPageID }_icon should be used to change the icon for the page with a specific ID. The default value is returned with the alch_default_page_icon hook. The passed value should be compatible with the $icon_url parameter of the add_menu_page function.

Example

We have an AO options page with the id of my-options-page, the code should look as follows:

function change_my_options_page_icon() {
    return 'dashicons-chart-pie';
}

add_filter( 'alch_my-options-page_icon', 'change_my_options_page_icon' );
