You can take reference from below code. It will provide an option to update user id of comment (https://prnt.sc/s57q4f). paste below code in active theme’s functions.php file.I have tested and it is working for me. let me know if it works for you.
# comment user id update metabox
function action_add_meta_boxes_comment( $comment ) {
?>
<div id="commnet-user-id" class="stuffbox">
<div class="inside">
<h2 class="edit-comment-userid"><?php _e( 'Commment User ID' ); ?></h2>
<fieldset>
<legend class="screen-reader-text"><?php _e( 'Comment User ID' ); ?></legend>
<table class="form-table editcomment" role="presentation">
<tbody>
<tr>
<td class="first"><label for="name"><?php _e( 'User ID' ); ?></label></td>
<td><input type="text" name="newcomment_userid" size="30" value="<?php echo esc_attr( $comment->user_id ); ?>" id="user_id" /></td>
</tr>
</tbody>
</table>
</fieldset>
</div>
</div>
<?php
};
// add the action
add_action( 'add_meta_boxes_comment', 'action_add_meta_boxes_comment', 10, 1 );
add_filter( 'comment_edit_redirect', 'save_edit_comment_data', 10, 2 );
function save_edit_comment_data( $location, $comment_id )
{
$_POST['user_id'] = (int) $_POST['newcomment_userid'];
wp_update_comment( $_POST );
return $location;
}
