I want to use this experience:

> **[A-Frame: Tap to Place Ground | 8th Wall | 8th Wall](https://www.8thwall.com/8thwall/placeground-aframe)**
>
> This example allows the user to grow cacti 🌵 by tapping or clicking the ground. Showcases raycasting, spawning objects, and importing a 3D model.

But I want to add buttons so the user can choose which object to place by tapping on the ground.  
Very similar to how the user chooses which video to play in this experience:

> **[A-frame: Change Alpha Videos | 8th Wall Playground | 8th Wall](https://www.8thwall.com/playground/alpha-video-change)**
>
> This example project allows the user to change through different SLAM based alpha videos.

But instead of using alpha videos, I would like the buttons to change models that I can make appear by tapping.

How can I do that? What code can I use?
