Is New-UDTabContainer valid in Powershell Universal?

A couple of questions. in working up a new dashboard in Powershell Universal I have the following code.

New-UDDashboard -Title 'PowerShell Universal' -Content {

New-UDTabContainer -Tabs {
    New-UDTab -Text "Applications" -Content {
        New-UDElement -Tag 'div' -Content { $gridapp 
        }
    }
    New-UDTab -Text "Database" -Content {
        New-UDElement -Tag 'div' -Content { $griddb }
    }
    New-UDTab -Text "Docker" -Content {
        New-UDElement -Tag 'div' -Content { $griddocker }
    }
    New-UDTab -Text "Mobile" -Content {
        New-UDElement -Tag 'div' -Content { $gridmobile }
    }
}

    
}


I am getting this error

- The term 'New-UDTabContainer' is not recognized as a name of a cmdlet, function, script file, or executable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again. at 1bedda39-cef5-4897-9f7e-e9fe283b48b9:1963

  1. Is New-UDTabContainer not part of Powershell Universal or am I missing something?

  2. can I define variables outside of the New-UDDashboard as i am doing with $gridapp, $griddb, etc?

It is New-UDTabs

Thanks much.
