How to retrieve the owner’s ID from the store?

In the user account, I created 2 display group_default and store_default

If I want to display group_default on the page of my group.

I added the code below in the model of my group and it works :

{{ drupal_entity('user', group.uid.target_id, 'group_default') }} 

I would like to do the same thing on the pages of my stores with the display store_default

But if I add the code below in the template of my store, it does not work :

{{ drupal_entity('user', store.uid.target_id, 'store_default') }} 

How to make the display of the owner of the store on the store page ?
