Doesn't seem to be working.

Since it may be a while before any PRs get accepted, you can use the existing plugin with the new backend like this
(in packages/backend/src/index.ts):

import { legacyPlugin, loggerToWinstonLogger } from '@backstage/backend-common';
import { createBackend } from '@backstage/backend-defaults';
import { coreServices, createBackendModule } from '@backstage/backend-plugin-api';
import { searchIndexRegistryExtensionPoint } from '@backstage/plugin-search-backend-node/alpha';
import { ConfluenceCollatorFactory } from '@k-phoen/backstage-plugin-confluence-backend';
...
const backend = createBackend();
...
backend.add(import('@backstage/plugin-search-backend/alpha'));
//backend.add(import('@backstage/plugin-search-backend-module-pg/alpha')); // if using pgsql search
backend.add(import('@backstage/plugin-search-backend-module-catalog/alpha'));
...
// Add Confluence collator to the search backend
backend.add(
    createBackendModule({
        pluginId: 'search',
        moduleId: 'confluence-collator',
        register(env) {
            env.registerInit({
                deps: {
                    config: coreServices.rootConfig,
                    logger: coreServices.logger,
                    discovery: coreServices.discovery,
                    scheduler: coreServices.scheduler,
                    indexRegistry: searchIndexRegistryExtensionPoint,
                },
                async init({ config, logger, scheduler, indexRegistry }) {
                    const defaultSchedule = scheduler.createScheduledTaskRunner({
                        frequency: { days: 1 },
                        timeout: { minutes: 15 },
                        initialDelay: { seconds: 3 },
                    });
                    indexRegistry.addCollator({
                        schedule: defaultSchedule,
                        factory: ConfluenceCollatorFactory.fromConfig(config, {
                            logger: loggerToWinstonLogger(logger),
                        }),
                    });
                },
            });
        },
    })
);
