How to limit Woocommerce wallet setting?

I already use this code but the problem is when the maximum amount of debit amount is bigger than the cart price, it won’t work. Ex: The product price is $10 but customer have $5000 in wallet.I limit the 20% of amount to deduct from wallet, Then it shows $1000 deducated from wallet but the product price is only $10.
For better understanding see the screenshot. Image: https://ibb.co/FJPNTp2
Please help me.

add_filter(‘is_valid_payment_through_wallet’, ‘__return_false’);
add_filter(‘woo_wallet_partial_payment_amount’, ‘woo_wallet_partial_payment_amount_callback’);
function woo_wallet_partial_payment_amount_callback($amount){
return (woo_wallet()->wallet->get_wallet_balance( get_current_user_id(), ‘edit’ ) * 20) / 100;
}

Finally, I found a code that works for me perfectly. But Some change needed. Can anyone change the code, please? In this code the 20% debited amount calculate from the total cart amount, but I want the 20% debited amount calculated from the total wallet amount.

add_filter(‘is_valid_payment_through_wallet’, ‘__return_false’);
add_filter(‘woo_wallet_partial_payment_amount’, ‘woo_wallet_partial_payment_amount_callback’, 10);

function woo_wallet_partial_payment_amount_callback($amount) {
if (sizeof(wc()->cart->get_cart()) > 0) {
$cart_total = get_woowallet_cart_total();
$partial_payment_amount = ($cart_total * 20) / 100;
if ($amount >= $partial_payment_amount) {
$amount = $partial_payment_amount;
}
}
return $amount;
}

Actually this is an important addition if it can be added to the plugin’s settings. Like allowing only up to 50% of the item’s value to be paid in wallet credits.
