This part should do what you want. Pcb view has been suppressed as not useful. You can drag an EZO board on to the connectors in breadboard and it will connect in schematic.
Apologies in advance for the simple question, but how does one edit components so an EZO circuit can be placed directly on the carrier board? I noticed the isolated carrier board functions differently where pins cannot be selected in the request below:
While it has been a while since I did the isolated version and I’m not sure if I configured it that way, you need to set the pins on the headers to type=female (as normal parts are type=male.) That does two things, blocks connections to the breadboards (because breadboard pins are also female) which is one of its uses and allows male pins to connect to them like a breadboard. The pins are likely active, they should connect if you attach a wire to them, they just are not highlighted when not connected and thus may look inactive.
