Event observer for multi select attribute in Magento 2

Question

I want to get new added option or all option at the time of save multiselect attribute from admin.

Which event I need to use for multiselect attribute save?

Answer 1

I have found the event which we use for attribute save

catalog_entity_attribute_save_after

Here we can get current attribute option by Magento\Catalog\Model\Product\Attribute\Repository

if ($attrCode == "MyAttribute")
{
    $attributeOptions = $this->repository->get($attrCode)->getOptions();
    ....
    ....
}
