Contact Form7' is not showing up in a static theme

Hi,
I have created a static theme https://www.sparrowacademy.com. You can see the website, it’s going fine. The problem is after installing and activating the plugin called ‘Contact Form7, the codes are not working when copied and pasted in static contact page/add new page. It not working in either ways.

Can you help me where I’m going wrong?
I will appreciate your help.
Regards,
Alex
