Mqtt Ring - alarm_control_panel.home_alarm not available

Hi, since mid-February the Ring Mqtt entity tells me “This entity is no longer served by the mqtt integration.” How come? How can I solve it? I installed “Manual MQTT Alarm Control Panel” and inserted this code into configuration.yaml as suggested, but I see what is attached but when pressed the alarm does not activate or deactivate, in short it doesn’t work. Is there any step I skipped? Thank you

alarm_control_panel:
