Add Attachment and Cc Parameter to smtp Email function - powershell

Question

My powershell script currently handles sending an email from the command line to a list of users. I would like to add an attachment to the email and also a list of Cc so all emails don't come through the "To" email parameter. Here is my current function.
function SendEmail
{
$smtpServer = "smtp.server"
$smtpFrom = "PROD <email#gmail.com>"
$smtpTo = "me#gmail.com"
$messageSubject = "Weekly List "+$day
$messagebody = "Hi User, Please find attached document. Thank you."
$smtp = New-Object Net.Mail.SmtpClient($smtpServer)
$smtp.Send($smtpFrom,$smtpTo,$messageSubject,$messagebody)
}
My attempt was to add a variable called $attachment = "\PathtoFile"
and add $attachment into the Send function, but that didn't work...

Use Send-MailMessage with the Attachments and Cc parameter:
Send-MailMessage -Attachments "C:\path\to\attachment.ext" -Cc "myboss#gmail.com"
You can also specify an encoding (you mentioned special characters):
Send-MailMessage -Encoding UTF8
In general, I would recommend splatting the parameters, so it ends up looking like this:
$MyAttachments = ".\a\relative\path.ext","C:\another\file.ext"
$MailParams = #{
SmtpServer = "smtp.server"
From = "PROD <email#gmail.com>"
To = "me#gmail.com"
Subject = "Weekly List "+$day
Body = "Hi User, Please find attached document. Thank you."
Attachments = $MyAttachments
Encoding = [System.Text.Encoding]::UTF8
}
Send-MailMessage #MailParams
