I have a 3 level deep taxonomy bundle which I want to use it as a select field in a custom form. I could not find any examples of how I can render the field in my custom form, I am able to get if I set "#type" as "entity_autocomplete". But it needs to be a select dropdown. Can anyone give an idea of how I can fix this?

$form['my_taxonomy_reference_field'] = [
'#type' => 'entity_autocomplete',
'#target_type' => 'taxonomy_term',
'#title' => $this->t('Country'),
'#default_value' => '',
'#selection_settings' => [
'target_bundles' => ['your_taxonomy_term_machineid'],
],
