Hello, we're new to Tealium and struggling to get some fundimental understanding of how to achieve certain things in the platform. In this usercase, we have a first-party cookie of "User" to which we'd like to map to our dataLayer. I'm assuming in this situation, we'd select First-Party Cookie? Is this correct? Or, does this process actually "write" a "new" cookie? If establishing the First-Party Cookie item in the dataLayer is correct, do we name this item "anything" we'd like or does it's name need to aling with the actual cookie name? I assume if the latter than this is how we pull in the cookie value? Is this correct? If not, I would have to guess we need to establish an extension to get the cookie value? I understand these may seem like pretty fundimental questions but I've struggled to find any basic information that completely explains how this works. Any feedback would be welcome.
