Current Code:
org.springframework.http.HttpHeaders;
HttpHeaders headers = new HttpHeaders();

headers. Set(Headers.AUTHORIZATION, Headers.BEARER + oAuth2RestTemplate.getAccessToken());

I need to get the Access Token using a RestClient and OAuth2OpaqueToken.

What should be the equivalent code?

My RestClient looks like below:
RestClient restClient = RestClient.create();

ResponseEntity response = restClient
.method(HttpMethod)
.uri(URI)
.headers(Consumer)
.body(Object)
.retrieve()
.toEntity(Class);
I am using spring-boot 3.2.6
spring-security 6.2.4; spring-security-oauth2 2.2.5.RELEASE; oauth2-resource-server 6.3.0; spring-security-oauth2-client 6.2.4; spring-security-config 6.2.4
