Setup proxy to invoke WCF service reference

I added a wcf service reference to external soap web service. It's all good until i publish the solution to an internal machine which need to setup a proxy (with Basic auth user/password) to be able to invoke WS.

In .net framework, it was just add a section config to setup the proxy. I need the same in a .net 6 project..
I already tried to create a CustomBinding object to wrap BasicHttpBinding, in order to set the proxy but without success...
Anybody can give me some tips to achieve that? Do you have any sample with this use case?

Thanks a lot.
