problem with payment opions on pay_for_order page

We have installed the woocommerce plugin for stripe payments and it works on our checkout but if an user want to use the pay now link on order confirmation email the pay_for_order page is shown only with the wire transfer option.

We have installed members because we manage also B&B orders who should only can pay with wire transfer. For this we have in our function.php following code which also works in checkout but block the payment options for all users in pay_for_order page.
Why does the pay_for_order page not check if the user is a member of a group? For open the page a login is necessary .

//Disable payment gateway Kreditkard - stripe  - paypal - for member of group Dealer
function my_creditcard_disable_manager( $available_gateways ) {
global $woocommerce;
if ( isset( $available_gateways['stripe'] ) && current_user_can('dealer')) {
unset( $available_gateways['stripe'] );
} 
if ( isset( $available_gateways['stripe_sofort'] ) && current_user_can('dealer') ) {
unset( $available_gateways['stripe_sofort'] );
} 
if ( isset( $available_gateways['stripe_ideal'] ) && current_user_can('dealer') ) {
unset( $available_gateways['stripe_ideal'] );
} 
if ( isset( $available_gateways['paypal'] ) && current_user_can('dealer') ) {
unset( $available_gateways['paypal'] );
} 

return $available_gateways;
}
 
add_filter( 'woocommerce_available_payment_gateways', 'my_creditcard_disable_manager' );

The page I need help with: [log in to see the link]
