Connecting different banking accounts to WIX

How can I link different banking accounts to WIX (not studio).

I connect users with different doctors/professionals and need that users pay directly the professionals (not the platform).

I need that the user books an appointment on WIX and pays directly the professional/doctor because the platform is not entitled to issue medical invoice.
However, WIX allows to connect only one banking account.

How to overcome this problem? Any external (cheap) tool to integrate in the User Experience or any code to modify?

Thank you

It seems to me that the simplest thing to do would be to link to each of the professionals represented on your website. I mean, after the person schedules, they are provided a link to pay the professional directly, either on the professional’s website or via their invoicing system. Otherwise, you become a middleman for the payment which could create a set of unforeseen problems.
