Reviews by user id

I have found from an old thread this shortcode that shows all the reviews

add_shortcode( 'reviews', 'show_reviews' );

function show_reviews() {?> <?php
    $args = array ('post_type' => 'product');
    $comments = get_comments( $args );
    wp_list_comments( array( 'callback' => 'woocommerce_comments' ), $comments);
?> <?php
}

but how could I make it show only logged in user’s reviews? I have tried the following

add_shortcode( 'my_reviews', 'show_my_reviews' );

function show_my_reviews() {?> <?php
    $args = array ('post_type' => 'product',
				 'user_id' => $current_user->ID );
    $comments = get_comments( $args );
    wp_list_comments( array( 'callback' => 'woocommerce_comments' ), $comments);
?> <?php
}

but didn’t work. Could you please help me?

Thank you!

You should set the variable $current_user before you use it:
$current_user = wp_get_current_user();

?> <?php is redundant.
