I’m a big fan of Firefox’s email mask feature. Not sure which update it was but recently it showed up when clicking on an email field. FF creates an email address for you and forwards any mail you get to your main email. It’s been great for signing up for random crap cus you can just delete the email mask “account” afterwards.
Does this help? https://spreadsheetpoint.com/insert-google-sheets-into-google-slides/
