Can I use ElasticSearchEngine() with the collection Meteor.users?

I want to know if there’s a way to use it because the error that appears is

uncaught Error: There is already a collection named "users/easySearch"

This is how I used it

export const UsersIndex = new Index({
    engine: new ElasticSearchEngine(),
    collection: Meteor.users,
    fields: ['profile.firstname', 'profile.secondname', 'profile.surname', 'profile.lastname', 'profile.Province', 'profile.assurances'],
})

And all of my users are stored in the meteor.users collection and I’ve been tasked to use only ElasticSearchEngine.

Any type of help is apprecciated.
