How to get a reference of which block entity this current view exposed form block belongs to in hook_form_views_exposed_form_alter().

$form_state->getFormObject() returns an object of Drupal\views\Form\ViewsExposedForm. This object doesn't have any reference to the $block.

I can get the block entity correctly inside hook_form_block_form_alter() by something like this:

$block = $form_state->getFormObject()->getEntity();

I wanted to modify the views exposed form based on a 3rd party value set on the block entity. But unable to do so, because I need to dynamically get the block id and not hardcode.
