Creates an OpenID Connect client. The client enables passwordless login with EUDI Wallet by requesting verifications from individuals. During client creation, a presentation definition specifies which credentials to request - appearing as a QR code or deep link on the authentication page.

A map of VCTs (verifiable credential types) to claim paths used as linking values for identity matching. Each key is the VCT of a credential, and the value is the dot-separated path to the claim within that credential to use as the linking value. Example: `{"https://example.com/vct/drivers-license": "email"}` maps the `email` claim from the drivers license credential for identity matching.
