Visual Tab for WooCommerce Products Not available

I understand that this theme do not have WooCommerce support and yet, I’m asking if that’s the reason for why the visual tab when editing products is inactive?

Changing themes resolves the issue which makes me wonder, can we add it like this:

function mytheme_add_woocommerce_support() {
add_theme_support( ‘woocommerce’, array(
‘thumbnail_image_width’ => 150,
‘single_image_width’ => 300,

‘product_grid’ => array(
‘default_rows’ => 3,
‘min_rows’ => 2,
‘max_rows’ => 8,
‘default_columns’ => 4,
‘min_columns’ => 2,
‘max_columns’ => 5,
),
) );
}
add_action( ‘after_setup_theme’, ‘mytheme_add_woocommerce_support’ );
