How to get Onvif sensor updates in mqtt broker

I have installed the Onviff integration running with one of my recently installed Dahua PoE cams and that seems to work ok. I get some sensors in the dashboard telling if there is motion or not. What I would have for a certain application, is the sensor state also sent to mqtt broker when it changes. How to get that? I was assuming it already did but seems not.
Any ideas how to get that?

Still interested to find out how to get the sensor update published to mqtt broker also. Anyone who has this running and willing to share how to get that? I’m new in HA and would be happy to get help. thanks.

Any help on this? I am very new to HA and have no idea where to start to get this sensor to output updates to mqtt for further use. Seems that it should not be that difficult. But as mentioned I am new with HA and a bit overwhelmed by all the possibilities. So maybe any one can give me some direction or use full topic / link to read or so. Thanks.
