Yes. The vox-l simulator that's in the browser when you complete these badges: https://mod.learntomod.com/badge_pointers/9054 should work, but if it doesn't you can unlock the vox-l artifact in the artifacts shop on the learntomod website (to get there, click the red square on the homepage). Then "buy" it -- there's no need to download it. Make sure it's enabled and when you go back to your badges, and refresh the badge page, your in-browser vox-l simulator should work.
If you see web unity not supported or 'please use a different browser' then that means you're not using the vox-l simulator. In that case, you need to press the skip simulator button and test in minecraft.
