Issue with 'name' field

Path: /self-hosting/single-sign-on

I try to use OIDC via Synology. Synology only supports the following claims:
"claims_supported" : [ "aud", "email", "exp", "groups", "iat", "iss", "sub", "username" ]
--> 'name' is missing

I can authenticate, but rallly stops with a "error=OAuthCreateAccount"
Log says

[next-auth][error][adapter_error_createUser] 
https://next-auth.js.org/errors#adapter_error_createuser

Could you eighter add a env-string like 'OIDC_USER_CLAIM' or in that case just use email as name if name is missing
