WebGl 2 is not defined in Google Chrome despite hardware acceleration enabled

I'm trying to use WebGL 2 on a website but I can seem to get it to work on my PC. Says it's not available. I can't figure out if it's the graphics driver or OpenGL's version, but here's some info. Any help will be highly appreciated.

Here is my hardware.

Chrome version: Version 108.0.5359.98 (Official Build) (64-bit)

lsb_release -a outputs:

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Linux Lite 5.6
Release:    20.04
Codename:   focal

lspci | grep VGA outputs:

00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)

glxinfo | grep 'version' outputs:

server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
    Max core profile version: 0.0
    Max compat profile version: 2.1
    Max GLES1 profile version: 1.1
    Max GLES[23] profile version: 2.0
OpenGL version string: 2.1 Mesa 21.0.3
OpenGL shading language version string: 1.20
OpenGL ES profile version string: OpenGL ES 2.0 Mesa 21.0.3
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 1.0.16

And here are the settings for chrome.

Report from WebGL Report

The answer can be found in your printout fragment Max GLES[23] profile version: 2.0, which is confirmed by this tech sheet. So your maximum supported Open GLES version is 2.0 which equals to WebGL (version 1). You would need a graphics controller which supports Open GLES 3.0 as that corresponds to WebGL2.

So, in short -- everything's fine with Chrome, but your hardware resp. its driver doesn't support Open GLES 3 and therefore not WebGL2.
