Add action fee before a plugin

I’m using the Woo Payment Discounts plugin which adds 5% discount to a certain payment method.
I’m also using a function in the functions.php file so that the customer gets 40% off from 10 items.

add_action( 'woocommerce_cart_calculate_fees', 'cart_items_quantity_discount', 10, 1 );

I would like to change the order in which discounts are applied.
First the 40% (from the functions.php file)
Then the 5% after choosing the payment method.

I already changed the add_action function call priorities and it didn’t work.

Does anyone have any tips on how to reverse the call order?
