From here, I selected one of the templates to use - I was then prompted to create an Atlassian account although I've been logged into my company's Confluence and using it for a while now. So I entered my company email address, the same one I use for that Confluence, but I was then prompted to create my own Atlassian website... Why wasn't my email address detected and automatically linked to my company's Confluence, and how do I utilize one of those templates to create a page there, in my company's Confluence spaces...?
