Add a user to multiple channels via Powershell

Hi,

I'm trying to customize a Powershell script to add one user to multiple channels at once. It will save a lot of work when there's a new employee.

This is my original script:

$channels = Import-Csv -Path “C:\Users\Administrator\Desktop\channels.csv” | select -ExpandProperty Channel
$grps=Import-Csv -Path “C:\Users\Administrator\Desktop\channels.csv” | select -ExpandProperty groupID
foreach($channel in $channels){
foreach($grp in $grps){
Add-TeamChannelUser -GroupId $grp -DisplayName "$channel" -user <>
}
}

It works flawlessly when the channel's display name doesn't have a space in between. If it does, there will be this error message "Channel not found". I tired the quotation marks but with no luck.

How can I make this work for channels with a space in the display name?

Any help will be much appreciated!
