plugins – register_activation_hook not working

I’ve a primary file for my plugin that comprises the next:

<?php
/**
Plugin data
 */

outline( 'PLUGIN__DIR', plugin_dir_path( __FILE__ ) );

require_once( PLUGIN__DIR . 'class.properties.php' );

// Init properties
add_action( 'init', array( 'properties', 'init' ) );

Inside the category that’s required I add a register_activation_hook that should create some tables. I observed no tables have been added so I attempted including a die() or wp_die() to see if it even comes there in any respect, however nothing occurs when activating the plugin.

So I’m guessing it by no means will get to the activation hook, however why?

What am I lacking?

My class that comprises the activation hook:

<?php

class Properties
{
    non-public static $initiated = false;

    public static operate init()
    {
        if (!self::$initiated) {
            self::initHooks();
        }
    }

    non-public static operate initHooks()
    {
        self::$initiated = true;
        register_activation_hook(PLUGIN__DIR, 'initTables');
        add_menu_page('Properties', 'Properties', 'manage_options', 'properties/overzicht', array(__CLASS__, 'propertiesIndex'), 'dashicons-admin-multisite', 6);
    }

    public static operate initTables()
    {
        wp_die();
