how to download all email attachments in "g suite" (fka 'google apps' and similar to gmail)

I usually use outlook, so forgive this dumb questions about gmail.  

I have g suite account which received 5 emails and each email has 10 attachments.

I want to download the attachments to my c drive.  

I have followed several links, but none seem to work.
For instance, one link  says highlight the thread then click "forward all" to  yourself, then receive the forwarded email, and click "download all".

But each email is independent, not part of a thread.

And, all is see is "forward", not a forward all.
