Welcome to the Make community!
Instead of using the Gmail “Watch Emails” module, use the Email “Get Emails” module.
This is because the Gmail integration does not have a search module.
I’m sure others would agree that this is a nice feature to have. You can submit this Gmail search module suggestion to the Idea exchange, under App improvement ideas.
Don’t forget to search for it first, just in case someone already suggested it, so that you don’t end up creating a duplicate.
