Expected behavior

Issuance of a VC by using authentication method 'VP_Token' works and requested VC is issued after presentation of the VP-Token

Actual behavior

Environment

Additional context

Checked the source code quickly and started wondering if authentication method 'VP_Token' is implemented, yet?
