Get DL Groups user is member of in Exchange online

I'm trying to get the list of DL groups user is member of in O365. I'm using below PS Script but I'm getting the error message.

$user = "test1@rtest.com"$dlGroups =Get-DistributionGroup | Get-DistributionGroupMember | Where-Object {$_.PrimarySmtpAddress -eq $userEmail}foreach($dl in $dlGroups){ Write-Output $dl#Remove-DistributionGroupMember -Identity $dl.Identity -Member $user}

error:

Write-ErrorMessage : ||The operation couldn't be performed because 'Bus Training School' matches multiple entries.
