Streaming video from uv4l to Blynk using nodered

I am able to stream video using uv4l and nodered on local server. Now I want to stream it to my phone using Blynk. I have a local Blynk server installed on my RPi3B+ and it works. On another RPi3B+ I have a rspicam and some sensors and actuators (and nodered) and would like to access them using Blynk on my phone. I was playing with node-red-contrib-blynk-ws, but no luck so far. Can anyone help me with streaming video to Blynk using nodered?
