How to populate the phone_international field type programmatically

Hi, here is my example

$countries = array_keys($this->countryManager->getList());
// Trim the required countries from excluded countries.
$excluded_countries = array_diff($countries, ['MD', 'RO']);
$form['blah']['contact_info']['phone_number'] = [
'#type' => 'phone_international',
'#title' => $this->t('Phone number'),
'#country' => 'MD',
'#geolocation' => TRUE,
'#exclude_countries' => $excluded_countries,
'#size' => 12,
'#maxlength' => 12,
'#countries' => ['MD', 'RO'],
'#placeholder' => '0XXYYYYYY',
];
