ServerHttpSecurity bean not found - spring

Question

I have a Security config class that has a SecurityWebFilterChain bean in it. This bean requires a ServerHttpSecuirty instance but spring says that it cannot find any beans of that type though there is one created in the external library (org.springframework.security.config.annotation.web.reactive.ServerHttpSecurityConfiguration). I have seen this issue on a github page and they said try a different version but I am using spring boot 2.4.5 so it should work.
My Security Config class:
#Configuration
public class SecurityConfig {
#Bean
SecurityWebFilterChain springWebFilterChain(ServerHttpSecurity http,
JwtTokenProvider tokenProvider,
ReactiveAuthenticationManager reactiveAuthenticationManager) {
final String TAG_SERVICES = "/api/**";
return http.csrf(ServerHttpSecurity.CsrfSpec::disable)
.httpBasic(ServerHttpSecurity.HttpBasicSpec::disable)
.authenticationManager(reactiveAuthenticationManager)
.securityContextRepository(NoOpServerSecurityContextRepository.getInstance())
.authorizeExchange(it -> it
.pathMatchers(HttpMethod.POST, TAG_SERVICES).hasAnyRole("USER","ADMIN")
.pathMatchers(HttpMethod.PUT, TAG_SERVICES).hasAnyRole("USER","ADMIN")
.pathMatchers(HttpMethod.GET, TAG_SERVICES).hasAnyRole("USER","ADMIN")
.pathMatchers(HttpMethod.DELETE, TAG_SERVICES).hasAnyRole("USER","ADMIN")
.pathMatchers(TAG_SERVICES).authenticated()
.anyExchange().permitAll()
)
.addFilterAt(new JwtTokenAuthenticationFilter(tokenProvider), SecurityWebFiltersOrder.HTTP_BASIC)
.build();
}
}
My application class
#ConfigurationPropertiesScan
#SpringBootApplication(exclude={DataSourceAutoConfiguration.class})
public class TestPlatformBackendApplication {
public static void main(String[] args) {
SpringApplication.run(TestPlatformBackendApplication.class, args);
}
}
External Library Bean:
#Bean({"org.springframework.security.config.annotation.web.reactive.HttpSecurityConfiguration.httpSecurity"})
#Scope("prototype")
ServerHttpSecurity httpSecurity() {
ServerHttpSecurityConfiguration.ContextAwareServerHttpSecurity http = new ServerHttpSecurityConfiguration.ContextAwareServerHttpSecurity();
return http.authenticationManager(this.authenticationManager()).headers().and().logout().and();
}

As Toerktumlare recommended in the comments (1, 2) I added #EnableWebFluxSecurity to my security config:
#Configuration
#EnableWebFluxSecurity
public class SecurityConfig {
But I also added the following to my exclude in the #SpringBootApplication annotation.
#ConfigurationPropertiesScan
#SpringBootApplication(exclude={DataSourceAutoConfiguration.class, SecurityAutoConfiguration.class, ManagementWebSecurityAutoConfiguration.class})
public class TestPlatformBackendApplication {
public static void main(String[] args) {
SpringApplication.run(TestPlatformBackendApplication.class, args);
}
}
