Filter entries of a relation field based on a field included in the related collection type

Hi all, I’m very new to Strapi and a self-taught developer so please bear with me, thanks in advance for any help.

I’m on Strapi v4.15.4 (node v20.8.0) and I created 2 collection types named user-test and article. user-test collection type has the following attributes:

"attributes": {
    "name": {
      "type": "string"
    "confirmed": {
      "type": "boolean"

In addition to that user-test collection type has 4 entries:

id name confirmed
1 User1 true
2 User2 true
3 User3 false
4 User4 true

article collection type has the following attributes:

"attributes": {
    "title": {
      "type": "string"
    "body": {
      "type": "blocks"
    "authors": {
      "type": "relation",
      "relation": "oneToMany",
      "target": "api::user-test.user-test"

I’d like to filter, when creating/editing an entry in the article collection type from the admin panel, the entries of the relation field authors so that only the users for which the attribute confirmed is true are shown. In other words, I’d like to see only User1, User2 and User4 as entries of the relation field authors.

For now, I edited src\api\article\controllers\article.js in order to filter the entries in the user-test collection type but I don’t know how to proceed from here. Also, I’m not sure why I cannot see anywhere the output of console.log(confirmedUsers).

'use strict';

const { createCoreController } = require('@strapi/strapi').factories;
const { sanitize } = require('@strapi/utils');

module.exports = createCoreController('api::article.article', ({ strapi }) => ({
    async getAuthors(ctx) {
      // Fetch confirmed users
      const confirmedUsers = await strapi.entityService.findMany('api::user-test.user-test', {
        filters: {
            confirmed: true,

Any advice is very much appreciated. Thank you.

Any suggestion? Thanks in advance!

Did you find any workaround?
