Does the Perspective App support WebGL?

I would like to know if the perspective app supports WebGL. I’m researching possibilities for the creation of a perspective map component. I need users to be able to draw selectable polygons on a map.

I was thinking to start here: and build it into a perspective component. It’s been built on top of MapBox GL JS, which uses WebGL.

An alternative would be to start with the Leaflet JS library, which is currently already used by perspective for its map component. I’m also considering to start from scratch with a simple react canvas polygon drawing tool:

The apps, as far as I know, just use the system’s embedded webview, which should support WebGL as long as it’s a fairly recent version.
