Target Display Mode not working 2019 iMac to 2013 iMac

I just brought home a brand new 2019 iMac, and I'm trying to use my Late 2013 iMac as a second monitor. Because the new iMac has USB-C, I have a USB-C-to-Thunderbolt adapter, and a Thunderbolt cord going into the old iMac. Pressing Command-F2 does not work (both with and without the Fn key). I have tried pressing it before login (at the login screen), and after I'm logged in. Tried it as a guest user as well. Nothing.

Is it the adapter that's getting in the way? I don't see any way to connect the two devices any other way. Little help, please?

Hi Wayne. I'm connecting a 2019 iMac to a 2013 iMac, which is supported. I finally got it working last night by playing around with the thunderbolt cord and plugging it into different ports. It eventually worked, now I just hope it keeps working because it sure didn't want to do it at first.
