Extending Display to a monitor from laptop

I have a Zorin OS 16.2 running on an Ideapad 5 15itl05,with MESA Intel UHD Graphics (ICL GT1). How can i connect a DELL S2421HN 1920x1080 monitor through HDMI cable?
Settings for Displays shows Built -in -Display Tab Only.

It really should be plug n' play.
Something must have gone wrong. Plug in the external monitor (Some HDMI cables are one direction only, so check the connection sides on the cable).
Can you please post the terminal output for

sudo lshw -C video

let's see if it is not claiming that display.
