Fatal error Undefined constant

Hi,

I’m using this code:

/**
 * Show payment buttons in cart for specific categories ID only
**/

add_filter( 'wc_braintree_cart_payment_gateways', function ( $gateways ) {

$categories   = [Reload,Recharges,Wiederaufladung,eSIM];

    // Loop through cart items
    foreach ( WC()->cart->get_cart() as $cart_item ) {
        // Check for product categories
	if ( ! has_term($categories, 'product_cat', $cart_item['product_id'] ) ) {

            $gateways = []; 
            break;
        }

    }
    
return $gateways;

} );

And I get:

Fatal error: Uncaught Error: Undefined constant “Reload” in /wp-content/plugins/code-snippets/php/snippet-ops.php(469) : eval()’d code:7 Stack trace: #0

It works fine if I use the code directly in functions.php

Thank you for your help,
