How the browser parses the geometry in the mapillary.js detection request?

Question

Mapillary (V4) API provides two surfaces for interacting with the data: vector tiles and entity endpoints. I want to parse the geometry in the detection request into a readable format.

I have converted the geometry in base64 format to utf-8 format, but don't know how to be able to convert to a readable format.

I see from the developer documentation that python can parse through mapbox-vector-tile, but I wonder what tool should I use to parse in the browser?
