Getting started with 8thwall and VPS Niantic

Hello,
I want to develop a project using WebXR(8thWall platform) and VPS. According to the website’s instructions, I should be able to open a geo browser from my editor, but I do not see that feature in my view. Also, if I want to clone some existing projects utilizing VPS, it says, “Cloning is not available.” Could you please help me? Do you have an idea why it fails?
