Issues with CLoudflare Purge module configuration specifications

Problem/Motivation

Configuration form on [/admin/config/cloudflare-purge-form] asks for the Zone ID (I could find this in Cloudflare dashboard) and the Cloudflare Authorization.

Can you please let me know where exactly to get this *Cloudflare Authorization* parameter so can be passed to [/admin/config/cloudflare-purge-form]

I can see Email ID, Global API Key, Origin CA Key under my profile on Cloudflare Dashboard, but not able to see the *Cloudflare Authorization*. I tried will all these options but its not working and giving this error

Do I need to create any such key newly in CLoudFlare dashboard?

Steps to reproduce

• Install the module
• Go to [/admin/config/cloudflare-purge-form]
• Add the required params in the form

Proposed resolution

One line documentation for what is *Cloudflare Authorization* and where can we get this info in Cloudflare dashboard?

Remaining tasks

User interface changes

On the form UI at [/admin/config/cloudflare-purge-form], we can have single liner help text for each text field. Something as specified in the screenshot here
