i am writing a script to create some doc on my website,
im using stepper that consist of 3 steps,

  1. name of doc,
  2. template to clone,
  3. which i face problem has 2 field email and role(editor-viewer)
    New-UDStep -OnLoad {
        New-UDStack -Content {
            # New-UDElement -tag 'div' -Content { "Previous data: $Body" }
            
            New-UDStack -Content {
                New-UDElement -tag 'div' -Content { "Enter your email" }
                New-UDTextbox -Id 'email' -Value $EventData.Context.email
            } -Direction column

            New-UDStack -Content {
                New-UDElement -tag 'div' -Content { "Enter your role" }
                New-UDSelect -Id "role"-Option {
                    New-UDSelectOption -Name 'viewer' -Value 'viewers'
                    New-UDSelectOption -Name 'editor' -Value 'editors'
                } -DefaultValue 'editors'
            } -Direction column
        } -Spacing 2 -Direction column
    } -Label "Step 3"

how can i make this step dynamic where to (+) button on click to add those 2 fields again and (-) button to delete specific user this button appears at every user info if we have 2 at least.
if someone knows how to do it or if it’s possible

$users = @() 

$addFieldButton = New-UDButton -Text "Add User" -OnClick {
  $newStack = New-UDStack -Content {
    New-UDElement -tag 'div' -Content "Enter your email"
    New-UDTextbox -Id ("email" + ($users.Count + 1))  
  } -Direction column

  $newStack += New-UDStack -Content {
    New-UDElement -tag 'div' -Content "Enter your role"
    New-UDSelect -Id ("role" + ($users.Count + 1))  
      -Option {
        New-UDSelectOption -Name 'viewer' -Value 'viewers'
        New-UDSelectOption -Name 'editor' -Value 'editors'
      }
    -DefaultValue 'editors'
  } -Direction column
}

i tried this but i don’t know how to append it
