Importing OBJ models into jit.gl.model

Hi all, I am working on a long-term 3d scanning project for our client and am having trouble importing 3D models in OBJ format from Artec Studio into jit.gl.model. I did a little search and found a thread on the forum https://cycling74.com/forums/importing-collada-models-into-jit-gl-model with a link to the wiki, but unfortunately, it doesn't work (or it's outdated). That thread advises using Blender to convert OBJ files to COLLADA extension. I have no experience with Blender, maybe someone will suggest another way to import OBJ models
Best regards
