Oauth2 token with non-standard prefix for scopes

The 3rd party Oauth2 resources server that I am required to use returns the scopes in the JWT token with a prefix of scp as in "scp": "read_notifications.v1". When spring security parses the JWT it returns an empty set of scopes.

Does anyone know of a way to customize the parsing of the token to include scp as an alias for scope

Yes I know ways to customize the parsing of tokens.

With Spring Boot Starters of mine

Sample for a reactive OAuth2 client

With com.c4-soft.springaddons.security.issuers[].authorities[] properties, you can configure an auto-wired authorities converter. Here, I just set scp as source for Spring Authorities, but you can also define a prefix (something like ROLE_ or SCOPE_) and force to upper or lower case.
