Service: Group - disappeared

I dont understand how it’s happened, but I cant find service.group
in Configutarion\ Settings\ Integrations\ Group - not present
In event logs nothing about it.
Is it possible to reinstall or restart it?

I have tryed clean HA 2022.3.6 install rpi3 x64 with no addons etc. Group service is not present and/or not available !
Is it bug or group service was deprecated?

For “idiots” like me in future dont forget to add in configuration.yaml:
group: !include groups.yaml
and create groups.yaml file
