NSPanel Pro API

Hi.

I integrated Reolink Doorbell to NSPanel Pro via adding RTSP (using Sub Stream, lower resolution).
Now on NSPanel PRO i can see Video/Audio without issue, lets say 3-5 sec delay between opening stream and showing it on display.
As Reolink doorbell is integrated to Home Assistant i know when someone rings the bell, and in this case i would like just to see video stream on NSPanel Pro. Is this possible to do it somehow with NSPanel API? Using camera-stream from NSPanel Pro API - SONOFF Official ?

Regards.
