I can't use this.

### Version of x-select:
v3.1.1
### Ember Version / Ember CLI Version:
ember-cli: 5.7.0
**Ember Version:** 5.7.0
**Ember CLI Version:** 5.7.0

### Expected Behavior
After install emberx-select, I am using this but I got error.
{{#x-select
value=model.countries
searchField="name"
placeholder="Choose Country"
selected=selectedCountry
as |xs|
}}
{{#xs.option value=1}}Active{{/xs.option}}
{{#xs.option value=2}}Inactive{{/xs.option}}
{{/x-select}}

Attempted to resolve `x-select`, which was expected to be a component, but nothing was found.

(Describe how things should work.)
I want to show country list.

How can I fix this?
