Calc Headers&Footers not showed on the file

I want to get a better understanding about how the Headers/Footers… feature in Calc works. On Microsoft Excel when you choose headers/footers it will show it on the screen. On LibreOffice Writer when you choose Headers/Footers it will be displayed on the file as well, but on calc, it doesn’t seem to show it anywhere. Where can I see the Headers/Footers I choose? Is there any way to show it on the file?

Thank you
