Hello everyone,

I have an issue with z-index. I tried so many things with the style but it don’t work.

New-UDButton -Text "Ouvrir la Modale" -OnClick {
    
    Show-UDModal -Content {
        New-UDTypography -Text "Actions disponibles" -Variant "h5" -Align "center"
        #New-UDStyle -Style '.MuiButtonGroup-grouped .MuiButtonGroup-root .css-r6z5ec .MuiPopper-root: {z-index: 1050;}' -Content{
            New-UDButtonGroup -Content {
                New-UDButtonGroupItem -Text 'Enregistrer' -Icon (New-UDIcon -Icon 'save') -Style @("" = "")
                New-UDButtonGroupItem -Text 'Copier le fichier' -Icon (New-UDIcon -Icon 'copy') 
                New-UDButtonGroupItem -Text 'Télécharger' -Icon (New-UDIcon -Icon 'download') 
            }
        #}
    } -Persistent
}
