Email field of "leads" missing in Actions of Workflow

Hi there,

I am not sure how to go about this.

I already read this one, but it is about conditions.

I want to use the leads email in the actions.
E.g. send an email to them or copy it to a contact.

But unfortunately the email field is missing in the dropdown-menu when creating a new dataset.
I already know that I need to create a contact to send an email with Workflow to the contact, but if I want to automate creating contacts from leads that is impossible…

How to go about this?
Thanks!
