How to fetch form values for Simple hierarchical select?

Question

I have referenced a field with taxonomy by using simple hierarchical module and now I have to fetch the options programmatically to perform some actions on them. I tried to fetch it like the below it didn't work out.

$form['field_delivery_methods']['widget']['#options'];

This worked on shs 8.x-1.0-alpha5 but after upgrading to shs 2.0.0-rc3 its not working. Does anyone help me in understanding the latest structure on how to fetch the options?

You can use field_info_field() or can list_allowed_values().

$field = field_info_field('field_name');
$allowed_values = list_allowed_values($field);
