Enqueue script globally

I’m not aware of any other way but to use both add_action lines, for a single function.

Example:

function my_enqueue_sripts_function_name(){
    
    // your enqueue logic here
    
}
add_action('wp_enqueue_scripts',    'my_enqueue_sripts_function_name' );
add_action('admin_enqueue_scripts', 'my_enqueue_sripts_function_name' );

There’s no rule that forbids you from adding the same function on multiple hooks.

Furthermore, if you need to know which action called the function, from within the function, you can use current_action() or current_filter()
