multiple queries

[SRYVPRASAD]

Trying user fireORM as much as I can Is there a way to do the below query 



```ts
repository = getRepository(ListEntity);	

async GetUserLists(req: Request): Promise<ListEntity[] | any> {
try {
const listsByAuthor = await this.repository.whereEqualTo(e => e.author.id, req['user'].signedUid).find();
const querySnapshot = await firestore_instance
.collection('lists').where('contributors', 'array-contains-any', [
{ id: req['user'].signedUid, access: 'view', email: req['user']?.email, status: 'accepted' },
{ id: req['user'].signedUid, access: 'edit', email: req['user']?.email, status: 'accepted' }
]).get();
const listsByContributors = querySnapshot.docs.map(doc => doc.data());
const mergedLists = [...listsByAuthor, ...listsByContributors];
return mergedLists;
} catch (error) {
throw error;
}
}
