How to make requests to "@connections" in java sdk2

I should use another client:

       try (val apiGateway = ApiGatewayManagementApiClient.builder()
                .region(Region.US_EAST_1)
                .endpointOverride(new URI("https://xxxx.execute-api.us-xxxx.amazonaws.com/xxxx"))
                .credentialsProvider(StaticCredentialsProvider.create(
                        AwsBasicCredentials.create("xxx", "xxxxx")
                )).build()) {
            return apiGateway.getConnection(GetConnectionRequest.builder().connectionId(connId).build()).toString();
        } catch (URISyntaxException e) {
            throw new RuntimeException(e);
        }
