Pulling Gmail "from:mailer-damon" and "from:postmaster" email data into google sheets? - email

Question

I came across the code below in an article. I tried to modify it (q: "from:mailer-daemon OR from:postmaster",) so that the code can pull from not only mailer-daemon, but also postmaster emails. However, it handled the data differently for postmaster emails (postmaster recipient emails were put into the "Bounce Reason" column along with the reason). I'd also like for it to pull from a label I've created in Gmail called "Delete from CMMC List", but I'm unsure how to do that.
The column names that data is being separated into are as follows:
Bounce Date
Email Recipient
Error Status
Bounce Reason
Gmail Link
Original code that needs modification:
/*
* Gmail Bounce Report
* u/labnol Feb 12, 2020
* Written by Amit Agarwal
* email: amit#labnol.org
* twitter: u/labnol
* web: www.labnol.org
*/
