Creating a button that emails a message but does not include the PDF

Once an employee completes a form, I'd like them to be able to click a button that simply emails a message to a designated recipient saying "The form has been completed." I do not want any data related to the PDF or the PDF itself to accompany the message. Also, I'd like to take advantage of the CC and BCC fields. Here's the script I'm using, but unfortunately it emails the PDF along with the message. Any way to adjust?? Thanks!

this.mailMail ({
cTo:
"name [at] company [dot] org", cSubject: "testing",cCc: "name2 [at] company [dot] org",cBcc: "name3 [at] company [dot] org", cMsg: "This is a test",});
