load my user_login from database into my acf select field code - wordpress

Question

I am trying to upload my user_login from database into acf select field, in var_dump my array result is working good, but nothing uploaded in my acf select field?
1. I added a custom field "ACF select field" in a product post.
2. I'm trying to load my options values from my database.
3. I used an array to get the user_login values from the database
function.php
add_filter('acf/load_field/name=chef', 'my_acf_load_chef_field');
function my_acf_load_chef_field( $field )
{
$user_fields = array( 'user_login');
$argu = new WP_User_Query( array( 'role' => 'chef' , 'fields' => $user_fields ));
$choices = $argu->get_results();
$field = array();
if( is_array($choices) ) {
$len = count($choices);
for($i = 0; $i < $len; $i++) {
array_push($field, ($choices[$i]->user_login));
}
}
// var_dump($field);
// exit;
return $field;
}
this is the var_dump result
array(5) {
[0]=> string(5) "Ahmed"
[1]=> string(5) "Khedr"
[2]=> string(4) "meme"
[3]=> string(5) "Menna"
[4]=> string(7) "mustafa" }
this is the array result that i want to load in acf field

Your don’t assign your choices to the field. Try this code:
if (is_array($choices)) {
// Clear the choices
$field[‘choices’] = [];
// Assign the data to the field
foreach ($choices as $choice) {
$field[‘choices’][$choice->user_login] = $choice->user_login;
}
}
