How to use the @nozbe/watermelondb/adapters/sqlite function in @nozbe/watermelondb

import appSchema from './schema/app';

import migrations from './model/migrations';

import { isIOS } from '../../utils/deviceInfo';

const appGroupPath = isIOS ? `${ RNFetchBlob.fs.syncPathAppGroup('group.ios.chat.rocket') }/` : '';

if (__DEV__ && isIOS) {
	console.log(appGroupPath);
}

			adapter: new SQLiteAdapter({
				dbName: `${ appGroupPath }default.db`,
				schema: serversSchema

			modelClasses: [Server, User],
			actionsEnabled: true
		})
	}

	get active() {
		return this.databases.activeDB;
	}

	get servers() {
		return this.databases.serversDB;
	}
