["BUG"] The tenant config selector isn't working properly

[efortish]

Describe the bug
In /admin/eox_tenant/route/1/change/ the tenant config selector is not working properly.

Also the config input field doesn't recognize the external key of the tenant config, you must use this number instead TenantConfig object (3):

Is it possible to use the external key instead?, that is confusing for new users trying to set the tenant's routes.

To Reproduce
Steps to reproduce the behavior

1. In the /admin/eox_tenant/route/1/change/ try to use the options available here:

2. It would allow you tu use the add_id_config (the green +) but not the other ones.

Expected behavior
The change_id_config is not available. I don't know if the expected behavior is to show a list of already settled tenant configurations or something else. For now, it doesn't show or allow anything.
The add_id_config is opening the popup /admin/eox_tenant/tenantconfig/add/?_to_field=id&_popup=1, is that the expected behavior?
The view_id_config is also not available even if the tenant config is already settled

Additional context
Unfortunately I was unable to reproduce a client's bug in my local, the bug happened in a client's redwood environment, we saw that the client tried to use the add_id_config and nothing happened (is supoosed to open a popup to set a new tenant configuration),
