WooCommerce filter and Gutenberg block

Hi, this is more question than an issue.
I’m starting my first WooCommerce since introduction of Gutenberg and i’m trying to make the right way.
This morning i ran into an issue i’m not sure how i’m supposed to deal with. I have to change “add to cart link” using “woocommerce_loop_add_to_cart_link” filter (as i always dit) but apparently, this filter is not triggered in the native Product Grid block. Do I miss something (cache, JS filter) ?

Thanks for your help.

Benoit.
