Buddypress custom fields when create new grup, no work

Question

I want add some custom field when i create new grup, (I used for countdown) but it does not work when create new group, it only works when edit groups.

And I have this code :

function save_custom_buddypress_group_textinput($group_id) {
    if ( isset($_POST['custom_group_textinput']) ) {
        if ( $group_id == 0 ) { 
            $group_id = buddypress()->groups->new_group_id; 
        }elseif(bp_get_current_group_id() > 0) {
            $group_id = bp_get_current_group_id();
        }
        $text_input_value = sanitize_text_field($_POST['custom_group_textinput']);  
        groups_update_groupmeta($group_id, 'custom_group_textinput', $text_input_value);
    }
}
add_action('groups_group_after_save', 'save_custom_buddypress_group_textinput');
add_action('groups_group_create_complete', 'save_custom_buddypress_group_textinput');
add_action('groups_group_edit_save_complete', 'save_custom_buddypress_group_textinput');```


 my code is designed to save custom fields in BuddyPress groups when a group is created or edited. However, i mentioned that it's not working when creating a new group. 

$group_id become 0 and not working

This is my final code:

// Funcția pentru adăugarea câmpului text la formularul de creare/actualizare al grupului
function custom_buddypress_group_textinput() {
    // Asigurați-vă că sunteți într-o pagină de creare sau editare a grupului BuddyPress
    if (bp_is_group_create() || bp_is_group_admin_page()) {
        $group_id = bp_get_current_group_id();
        $custom_group_textinput = groups_get_groupmeta( $group_id, 'custom_group_textinput' );
        ?>
        <label for="custom_group_textinput">Time Remaining:</label> <?php // echo strtotime($custom_group_textinput); // timestamp ?>
        <input type="datetime-local" name="custom_group_textinput"  id="custom_group_textinput" value="<?php echo $custom_group_textinput; ?>" required />
        <?php
    }
}
add_action('bp_after_group_details_creation_step', 'custom_buddypress_group_textinput');

function save_custom_buddypress_group_textinput($group_id = 0, $group = null) {
    if ( isset($_POST['custom_group_textinput']) ) {
        if ( $group_id == 0 ) { 
            $group_id = buddypress()->groups->new_group_id; 
        }elseif(bp_get_current_group_id() > 0) {
            $group_id = bp_get_current_group_id();
        }
        $text_input_value = sanitize_text_field($_POST['custom_group_textinput']);  
        groups_update_groupmeta($group_id, 'custom_group_textinput', $text_input_value);
    }
}
add_action('groups_group_after_save', 'save_custom_buddypress_group_textinput');
add_action('groups_created_group',   'save_custom_buddypress_group_textinput');
add_action('groups_group_create_complete', 'save_custom_buddypress_group_textinput');
add_action('groups_group_edit_save_complete', 'save_custom_buddypress_group_textinput');
