Serching by role mongoose - node.js

Question

I am trying to retrieve users based on role but with every role queried, I want to also retrieve admin too. I am not sure how to go about it. This is how I currently retrieve based on role
public async listAllStaffs(query: ListStaffsRequestQueryDTO) {
var conditions = { }
if (query.role) {
conditions = { role: query.role, 'hub.id': query.merchant };
} else {
conditions = {'hub.id': query.merchant };
}
const data = { page: query.page, limit: query.limit, conditions: conditions};
const all = await this.list(data);
const pagination = {
page: all.page,
limit: all.limit,
rowCount: all.rowCount,
pageCount: all.pageCount
};
const staffs = all.staffs;
return { staffs, pagination };
}
async list(query: PaginationQuery): Promise<any> {
const page = Number(query.page) - 1 || 0;
let limit = Number(query.limit) || 20;
const offset = page * limit;
const sort = query.sort || 'createdAt';
const archived = this.convertArchived(query.archived);
const conditions = {
...query.conditions,
...(!archived
? { deletedAt: undefined }
: { deletedAt: { $ne: undefined } })
};
const staffs = await this.model
.find(conditions)
.select(query.projections)
.skip(offset)
.limit(limit)
.sort(sort);
const totalDocuments = await this.model.countDocuments(conditions);
const result = {
staffs,
page: Number(page) + 1,
limit: Number(limit),
rowCount: Number(totalDocuments),
pageCount: Math.ceil(Number(totalDocuments) / limit)
};
return result;
}
So if role is operation for example, I want to also return users with admin
So you have both operation staff and admin staff returned.

Use $in operator, to look for users in multiple roles, like this:
if (query.role) {
conditions = { role: { "$in": [query.role, "admin"] }, 'hub.id': query.merchant
};
}
