Home Page Slider Call-to-Action

I recently removed the default call-to-action button on the homepage slider, but would like to get it back. I use Customize and the URL for the button is: #primary

Is this correct? When I enter text, nothing happens.

yes, that is correct. the #primary is indicating to display the first content of your homepage. So, please make sure you have a content on your home page

Thank you, Awan!
