Hi @federico242,
The custom /ppcp-paypal-payment-tokens/
endpoint is only a temporary solution for users to be able to remove the saved payment methods.
The goal is to display the saved payment methods in the default /payment-methods/
tab instead but there have been some limitations with this endpoint.
In any case, for now, there is no filter to easily display the saved methods in a different section like the account details.
This would is not how WooCommerce handles it by default and would need a custom module with more custom code to achieve.
The current menu is created here, where you could see more about how it works.
I left a note in the issue to check whether or not a filter could be implemented for the renderer When this endpoint gets reworked. For now, there are no plans for this though.
Kind regards,
Niklas
