DBManager don't use authcfg with Oracle provider

[naub1n]

What is the bug or the crash?

I have an Oracle connection that use an authentication config with basic auth.
When I open the connection in QGIS Explorer, everything work fine.

But when I try to open the same connection with Db Manager, QGIS ask username and password because connection failed:

Steps to reproduce the issue

1. Configure Oracle connection with authentication configuration (basic auth in Password Manager).
2. Try to open the connection in DB Manager

Same result with QGIS 3.38.0

Issue exist with 3.28.9 and QGIS 3.34.11.
I also think that authentication configuration should be used in DB Manager. Now DB Manager asks username and password and if I then add layer using DB Manager QGIS stores my db credentials to project file.
