How could I style only specific points, for example the first point in a vertex and the rest.

Nobody has claimed this yet.

I would like to style only the first point in a vertex, as well as the remaining.
I understand is using something like this:

// vertex points HERE IS WHERE WE NEED TO FILTER THE POINT.
{
id: "gl-draw-polygon-and-line-vertex-active",
type: "circle",
filter: [
"all",
["==", "meta", "vertex"],
["==", "$type", "Point"],
["!=", "mode", "static"],
],
paint: {
"circle-radius": 8,
"circle-color": "#D20C0C",
},
},

but I can't find any example of being able to filter particular points ie: the first only, the remaining, second third... so forth.

Any help thank you ahead of time

Start with the `gl-draw-polygon-and-line-vertex-active` layer filter shown in the issue and inspect how vertex point properties are exposed to Mapbox GL styling. Determine whether point order can be used for filtering, then establish a supported way to style the first vertex separately from the remaining vertices and verify both styles in a drawing.
