Exposed filter block not showing up

Hi,

After I selected the option “Exposed form in block” in the Views module, I expected the form would be become available as a block.
Unfortunately, when i go to /admin/structure/block , the form isn’t visible anywhere.

Am I doing something wrong?

Thanks in advance.
