Not able to create form field using FieldStorageConfig and FieldConfig

Question

I am creating a custom form and want to render the form field using the FieldStorageConfig and FieldConfig. Fields (my_field) could be any type those are supported by FormAPI.

$field = FieldStorageConfig::loadByName('node', 'my_field');
$field_instance = FieldConfig::loadByName('node', 'my_content_type', 'my_field');

$form['duplicate'] = [
  '#title' => 'Get the title form my_field',
  '#type' => 'Get the type form my_field',
  '#other_properties' => 'Get all form element properties'

];
