Try switching it to WiFi preferred instead of Cellular Network Preferred and see if that helps.

thanks for the suggestion, I tried but my carrier doesn't offer that option and now I understand why.

After testing in airplane mode and turning on Wi-Fi, WiFi calling started working!

Glad you got it working 👍🏾

Well yeah if WiFi was turned off - That'd be a problem 😉
Good to hear you figured it out 👍
