Placing cylinder on featurelayer from array of client-side features

I'm testing the Javascript API for a project and am trying to place some features on a featurelayer as an array of client-side features. Normal polygons work well, but I can't find the correct way of placing a circle (extruded to make a 3D cylinder). In my mind the array would look something like this:

const cylFeatures = [ { geometry: { type: 'circle', center: [10.296842,61.313066], }, attributes: { objectID: 200, elevation: 390, height: 5, width: 12 } } ]

And then use unique value renderer to apply the width, height and elevation to the circle features. But this doesn't work of course. According to the documentation it seems like I can't use the circle type at all here.

I'm looking for clues to how I can do this.

For 3d points, you'll want to use an ObjectSymbol3DLayer. Here is a sample showing how it works.

Thank you for your reply! I will look into this solution. For now I have made my cylinder by making a circular polygon (using turf.js) and extruding that.
