PS script to bookmark URL in IE - powershell

Question

I have written a PS script which will create bookmarks in IE. I need to execute below command before running the ps script.
Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass -force
How can I avoid executing above cmd before executing ps script? Or Can anyone suggest me to convert this as .exe or .bat file?
And this script fails if Favourites folder doesn't exist and how can I avoid using favourites folder in this script.
My PS script:-
function create-bookmarks{
$bookmarks = #{
"folder1" = #{
"Jenkins" = "https://jenkins.net";
};
"folder2" = #{
"Jenkins" = "https://jenkins.net";
};
}
foreach ($Name in $bookmarks.keys)
{
$IEFav = [Environment]::GetFolderPath('Favorites','None')
New-Item $IEFav\$Name -ItemType Directory -Force
$Shell = New-Object -ComObject WScript.Shell
$IEFav = Join-Path -Path $IEFav -ChildPath $Name
foreach ($key in $bookmarks[$Name].keys)
{
$FullPath = Join-Path -Path $IEFav -ChildPath "$($key).url"
$shortcut = $Shell.CreateShortcut($FullPath)
$shortcut.TargetPath = $bookmarks[$Name][$key]
$shortcut.Save()
}
}
}
create-bookmarks
Error if Favourite folder does not exists under c:/users/username/Favourites.
