change woocommerce button text "select options"

Hi!
I can’t seem to find the place where to edit the “select options” button on my products.
I checked some solutions already but all didnt work.
Please give me a hint.
An example you can find on my homepage.
I will link it in Private Content Field

I tried loco translate,
And in Childtheme i tried to add this code to function.php:
add_filter( ‘woocommerce_product_add_to_cart_text’, function( $text ) {
global $product;
if ( $product->is_type( ‘variable’ ) ) {
$text = $product->is_purchasable() ? __( ‘Custom options text’, ‘woocommerce’ ) : __( ‘Read more’, ‘woocommerce’ );
}
return $text;
}, 10 );

Thank you very much
