Does Ember Octane Route class support using mixins?

I am upgrading to Ember Octane and I understand that mixins have been deprecated. I will continue to use them until I figure out how to replace them. In the meantime, I would like to switch my route over to using the new class syntax, as opposed to Route.extend. Does the new route class syntax support route mixins? If yes, how?

Pre-ember Octane:

import Route from '@ember/routing/route';
import AbcAuthenticatedRouteMixin from '../../mixins/abc-authenticated-route-mixin';

export default Route.extend(AbcAuthenticatedRouteMixin, {

    model() {

        return {
            oldPassword: '',
            newPassword: '',
            confirmPassword: ''
        };
    },
})

Post-ember Octane:

import Route from '@ember/routing/route';
import AbcAuthenticatedRouteMixin from '../../mixins/abc-authenticated-route-mixin';

export default class ChangePasswordRoute extends Route(AbcAuthenticatedRouteMixin, {

    model() {

        return {
            oldPassword: '',
            newPassword: '',
            confirmPassword: ''
        };
    },
}) // I get an error here that says: '{' expected
