Unable to create/custom Process documentation template

Hi Team,

I have a trial version of Signavio account created. While exploring the Process Manager tool, I wanted to create a new template for documentation. However, I am unable to find any template folder in the setup menu. I referred to the link here for the same : https://documentation.signavio.com/suite/en-us/Content/process-manager/userguide/workspace-admin/create-process-documentation-templates.htm#create_doc_templates

Kindly help.
