Identify Authentication Service - Establish Trust with IdP using OAuth2.0/OIDC

I have established an Identity Authentication Service tenant and have "connected" it to a BTP subaccount (i.e. - the tenant is present in "Trust Configuration"). I am now attempting to define an IdP as a "Corporate Identity Provider" that has an OIDC/OAuth2.0 interface, but my attempts have been unsuccessful . Note that the IdP does not provide a SAML interface. The IdP's OIDC "well-known/openid-configuration" interface is as follows...

// https://some-idp.com/some-idp-tenant/.well-known/openid-configuration
{
  "authorization_endpoint": "https://some-idp.com/some-idp-tenant/oauth2/authorize",
  "id_token_signing_alg_values_supported": [
    "RS256"
  ],
  "issuer": "https://some-idp.com/some-idp-tenant",
  "jwks_uri": "https://some-idp.com/some-idp-tenant/.well-known/jwks.json",
  "response_types_supported": [
    "code",
    "token"
  ],
  "scopes_supported": [
    "openid",
    "email",
    "phone",
    "profile"
  ],
  "subject_types_supported": [
    "public"
  ],
  "token_endpoint": "https://some-idp.com/some-idp-tenant/oauth2/token",
  "token_endpoint_auth_methods_supported": [
    "client_secret_basic",
    "client_secret_post"
  ],
  "userinfo_endpoint": "https://some-idp.com/some-idp-tenant/oauth2/userInfo"
}

Questions:

1) Given the above IdP OIDC/OAuth2.0 interface, is it possible to establish a trust relationship between SAP Identity Authentication Service and this IdP?
2) If so, can you please provide guidance on the (minimal) "Trust" configuration parameters (i.e.- "Subject Name Identifier", "Enriched Token Claims", etc.) that are required to establish the trust relationship?

Thank you.
