Oracle fusion Visual Builder create Service Connection for Bank account

Summary:

I want to create an AppUI to enter a Bank account.
In Visual Builder Studio I clicked on "Services" and then the "+" sign and picked Service Connection.
As Source I picked "Select from Catalog".
Then i clicked "Human Kapital Management".
Here i searched for "Bank" or "Account" or "Details".

I haven't found the endpoint.

Do you know how I upgrade the employees Bank Account Infos on a custom page?

Best regards
