How to leave one or more options preselected (ion-option)

Question

I have an array that I fill with service data from the database. And I also have a relationship table in the database between user and service. I would like to mark as selected the options that the user has set in the bank as the provider of that service.

Code listing the available services the person can provide:

<ion-option *ngFor="let service of services" value={{service.id}}>{{service.description}} </ion-option>

I already have an array with the services that the person provides, just check the checked option, how can I do this?
