How to use this plugin on Contact form 7

Hi there,

I have a contact from on this page – https://www.healyconsultants.com/contact-us/

I have been receiving a lot of spam inquiries via this contact form.

I installed your plugin and activated it.

I used the same spam inquiry to test the plugin.

But I am still receiving the spam.

Here is the spam inquiry

How should I use this plugin on contact form 7 ?
