Description
If we publish Issuer Metadata that contains a credential configuration with the following:
"credential_signing_alg_values_supported": [
"ES256", "ES256K", "RS256"
]
how do we know which signature alg to use when signing the credential for a particular wallet?
Is there a mechanism where the wallet chooses one of the supported values that I am missing in the spec, or is this out of scope and should be handled on some other level?
Thank you

Research direction
Start with the Issuer Metadata credential configuration and the credential_signing_alg_values_supported field described in the issue. Read the surrounding specification text and comment discussion to determine whether the wallet selects an algorithm or the issuer does. Done means the specification clearly documents the selection mechanism or states that it is out of scope.
