Hi @Mohammed Zuber Miyanavar

Run the below command to get the members of the DL

Get-DistributionGroupMember -Identity "Name" | select Name >c:\Users.csv
Import-csv C:\users.csv | foreach-object {Add-ADPermission -Identity "DGName" -User $_.Name -ExtendedRights "Send As"}

You can use Add-RecipientPermission incase if the users are in Exchange Online
