How could I upgrade to OpenGL 3.3?

SOULUTION: Executing the command that doug provided in the comments worked for me MESA_GL_VERSION_OVERRIDE=3.3 ./cascadeur

I want to run a program called Cascadeur on my Ubuntu 18.04.4 LTS machine.

When I try to run it it displays de following: Cascadeur requires OpenGL version 3.3

The output produced by the command glxinfo | grep OpenGL is the following:

OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 620 (KBL GT2) OpenGL core profile version string: 4.6 (Core Profile) Mesa 20.0.8 OpenGL core profile shading language version string: 4.60 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 3.0 Mesa 20.0.8 OpenGL shading language version string: 1.30 OpenGL context flags: (none) OpenGL extensions: OpenGL ES profile version string: OpenGL ES 3.2 Mesa 20.0.8 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20 OpenGL ES profile extensions: 

From the intel support webpage we know that it supports OpenGL 4.4

How should I proceed?
