Trying to Convert Lead into Contacts using Automation

Trying to Convert Lead into Contacts using Automation

Hi All - 

Hope you can help you.

I created a new rule to convert Lead to Contact if I do not receive an email from a lead after 7 Days/1 Week.
Sadly the only Instant Action I can choose is Create Record = Contact and no Convert showing.

My main goal is to convert that Lead into a Contact.

Best Regards
