No provider of glTextureSubImage2D found

When trying to run gtk4-widget-factory using the OpenGL renderer I get the following error message:

No provider of glTextureSubImage2D found.  Requires one of:
    Desktop OpenGL 4.5
    GL extension "GL_ARB_direct_state_access"
Aborted (core dumped)

What is the mimimum OpenGL version required for the OpenGL renderer?
Requiring OpenGL 4.5 seems a bit pointless to me, since all graphics cards supporting OpenGL 4.5 could probably also use the Vulkan renderer.
I'm interested in having the OpenGL renderer work on OpenGL 2.x / OpenGL ES 2.0 but right now it doesn't work on such hardware.
