Using woocommerce functions inside a custom shortcode

I am developing a custom plugin.

The main purpose of this plugin is to create a custom shortcode.

Inside callback function of this plugin, I use some of woocommerce functions. But I get “call to undefined function (any woocommerce function)” error.

For sake of simplicity, I created a very basic plugin to describe this problem.

<?php  

add_shortcode('custom_shortcode','custom_shortcode_callback');

function custom_shortcode_callback(){

    $order_id = 81201; 
    $order = wc_get_product($order_id);
    echo 'anything';

}

?>

I get this error: Uncaught Error: Call to undefined function wc_get_product().

In?some?answers?regarding?this?problem,?the?solution?was?to?hook?‘woocommerce_init’ or ‘woocommerce_loaded’?actions.?But?I?want?to?echo?some?result?in?page?and?just?hooking?to?these?actions,?does?not?provide?my?shortcode’s?intention.

I use this shortcode inside a WordPress page editor like this:

[custom_shortcode]
