Access hasMany/belongsTo relationship data with JSONAPI

Hey guys! Can you help me, please?

I have a model Channel, a model Feature, a model ChannelApplication and a model ApplicationFeature. And I defined them like this:

My model channel.js:

import Model from 'ember-data/model';
import attr from 'ember-data/attr';
import { hasMany } from 'ember-data/relationships';

export default Model.extend({
  name: attr('string'),
  key: attr('string'),
  multiplePages: attr('boolean'),
  features: hasMany('feature', { async: true })
});

My model feature.js:

import Model from 'ember-data/model';
import attr from 'ember-data/attr';
import { hasMany } from 'ember-data/relationships';

export default Model.extend({
  name: attr('string'),
  key: attr('string'),
  applicationFeatures: hasMany('application-feature', { async: true }),
  channels: hasMany('channel', { async: true })
});

My model channel-application.js:

import Model from 'ember-data/model';
import attr from 'ember-data/attr';
import { belongsTo, hasMany } from 'ember-data/relationships';

export default Model.extend({
  name: attr('string'),
  clientId: attr('string'),
  channel: belongsTo('channel'),
  applicationFeatures: hasMany('application-feature', { async: true })
});

My model application-feature.js

import Model from 'ember-data/model';
import attr from 'ember-data/attr';
import { belongsTo } from 'ember-data/relationships';

export default Model.extend({
  scope: attr('string'),
  connectType: attr('string'),
  channelApplication: belongsTo('channel-application', { async: true }),
  feature: belongsTo('feature', { async: true })
});

I'm using JSONAPI. And in my route I do this:

model() {
    return Ember.RSVP.hash({
      profiles: this.store.findAll('profile'),
      channels: this.store.findAll('channel'),
      channelApplications: this.store.query('channel-application', { filter: { feature: 'inbox'} })
   })
}

So, in my template I need to get my ChannelApplications and for each one I need to know Channel related with this ChannelApplications and know each ApplicationFeature.

{{#each channelApplications as |channelApplication|}}
    {{channelApplication.id}}
    
    // I think in something like this, but this doesn't work of course
    {{#each channelApplication.channels as |channel|}}
       <span>{{channel.id}}</span>
       <span>{{channel.name}}</span>
       {{#each channelApplication.applicationFeatures as |applicationFeature|}}
          <span>{{applicationFeature.id}}</span>
          <span>{{applicationFeature.name}}</span>
        {{/each}}
    {{/each}}

{{/each}}

channelApplication.applicationFeatures and channelApplication.channels returns nothing.

When I print {{channelApplication.applicationFeatures.length}} it return 0.

When I print {{channelApplication.applicationFeatures}} it prints a <DS.PromiseManyArray>

JSONAPI return for channelApplications: this.store.query('channel-application', { filter: { feature: 'inbox'} }):

So, someone know about anything I'm doing wrong, please?
