WebGL and 3D in Tor browser

Good afternoon
I downloaded the Tor browser to access the site https://cad.onshape.com. This online service is for 3D design. I can log into my account through the Tor browser, but the browser cannot display 3D objects. I’ve already read that WebGL doesn’t work well in the browser.
How can I enable full 3D modeling support in the tor browser? I’ve also read that it increases the ability to leave imprints. For the above site, I don’t care.
