How to get a list of all users and other queries through mongoose?

Question

Mongoose

There is a Mongo database with this schema:
let reportSchema = new Schema({
ssoid: {type: String},
ts: {type: Date},
grp: {type: String},
type: {type: String},
subtype: { type: String},
url: {type: String},
orgid: {type: String},
formid: {type: String},
code: {type: String},
ltpa: {type: String},
sudirresponse: {type: String},
ymdh: {type: String}
});
ssoid - Unique identifier of users
ts - Time (unix time)
grp - Event group
type - Event type
subtype - Event subtype
url - Address from which the event came
orgid - Organization providing the service
formid - Form identifier
ltpa - Session key (empty in this set)
sudirresponse - Response from the authorization service (empty in this set)
ymdh - Date in YYYY-MM-DD-HH format
Three queries must be executed, in the database via mongoose:
1. Display a list of users (by ssoid) and the forms they used in the last hour.
2. Display a list of users who started activity on the form and did not reach the end. For example, for grp services: guis_-47 start state start, end state send. Print at what step you stopped.
3. Make TOP - 5 most used forms.
The entries themselves look like this:
