function Invoke-WPFUIElements {
    <#
    .SYNOPSIS
        Adds UI elements to a specified Grid in the WinUtil GUI based on a JSON configuration.
    .PARAMETER configVariable
        The variable/link containing the JSON configuration.
    .PARAMETER targetGridName
        The name of the grid to which the UI elements should be added.
    .PARAMETER columncount
        The number of columns to be used in the Grid. If not provided, a default value is used based on the panel.
    .EXAMPLE
        Invoke-WPFUIElements -configVariable $sync.configs.applications -targetGridName "install" -columncount 5
    .NOTES
        Future me/contributer: If possible please wrap this into a runspace to make it load all panels at the same time.
