url always null

[new-user-name]

Describe the bug
Can not change url

To Reproduce
My setup()

setup() {
    const query = ref('');
    const suggestion = ref(undefined);
    return {
      token: import.meta.env.VITE_APP_DADATA_API_KEY as string,
      query,
      url: 'https://suggestions.dadata.ru/suggestions/api/4_1/rs/findById/party',
      suggestion : {
        count: 3,
        url: 'https://suggestions.dadata.ru/suggestions/api/4_1/rs/findById/party'
      },
    };
  },

Expected behavior
url is expected to be set

Screenshots
But it doesn't (see attach).

Desktop (please complete the following information):

Windows 11, 
"typescript": "^4.6.3",
        "vue": "^3.2.45",
        "vue-dadata": "^3.0.0-beta.9",
        "vue-debounce": "^4.0.0",
        "vue-loader": "^17.0.1",
        "vue-word-highlighter": "^1.1.2"

It's strange, but the token is somehow set, so I can change it

It seems url has to be passed as prop, not as property of suggestion...
