New-UDAvatar -Variant

I did spot this thread: Universal Dashboard v3 Progress
Where the style param is being used to set the height and width, but I cant see that the -style parameter currently exists on the latest version.

I can also see that alon uses

avatars = @{
            small = @{
                width = '24px'
                height = '24px'
                margin = '16px'
                borderRadius = '50%'
            }
            medium = @{
                width = '48px'
                height = '48px'
                margin = '16px'
                borderRadius = '50%'
            }
            large = @{
                width = '96px'
                height = '96px'
                margin = '16px'
                borderRadius = '50%'
            }
        }  

In his theme, I did try this but couldnt get it to function either, I have to admit though I’m a bit hazy on the how to and struggle with theming.
