Creating a conversion event for first time callers in GA4
I'm trying to set up first time callers from CallRail as a conversion event in Google Analytics 4. I followed the steps in https://support.callrail.com/hc/en-us/articles/9495611166733-Google-Analytics-4-Integration to do the CallRail integration and am seeing phone_call events triggering as well as the first time caller custom parameter when I click through to the phone call events.
What I want is for those first time callers to be counted as a conversion event. I've tried a few things, but none of them have worked, so I figured I'd see if anyone here has any ideas. What I thought it should be would be a setup like the screenshot below, but it's not being triggered, even as new callers come in. Is there something I'm missing?
