Viewing Ubuntu 22.04 Desktop from Android over WiFi

Given:

• a desktop with Ubuntu 22.04;
• a device with Android OS;
• WiFi network to which the desktop and the device are connected.

I need to share Ubuntu screen to Android over WiFi, thus, installed bVNC on Android. I tried to play with Ubuntu Remote Desktop and bVNC settings but without luck. Each time, bVNC shows a connection failed error.

So, my question is: how to share my Ubuntu desktop with Android over WiFi? I need it for viewing only (not controlling).
