If you are not seeing the option to turn on WiFi calling for the Idea SIM then the phone probably needs a firmware update to enable support and the operator should also whitelist your phone model number for VoWiFi support. Only then it would work.
My Redmi Note 8 Pro did show the toggle option for WiFi calling when I had inserted a Vi SIM.
