Is an MX record required for domain alias?

Hi, I've added my domain alias in Google Workspace, but I'm unsure of what to do next. I don't want to setup Gmail for the alias, I just want all emails sent to users at that to go to the same user at the primary domain. The domain alias is a subdomain. 

Primary domain: example.com

Domain alias: one.example.com

I presume I need to add an MX record so that email to user1@one.example.com goes to user1@example.com - is that right?

Thx
