Unable to add / discover Google mini in Home Assistant

Tags: #<Tag:0x00007f32716fbe18>

Currently on version 0.109.1 of Hass.io
Have the following settings in configuration.yaml.

  - platform: cast

I have a google mini configured on my Google Home App and can connect to the same via the Google Home app.

However the above device is not discovered in HA after I restarted the server.

Any luck? I have the same issue
