How to export colliders

Questions

Hello. I create colliders as objects to export them to JSON:

I can read collider positions and sizes from JSON:

         "name":"Colliders",
         "objects":[
                {
                 "class":"",
                 "height":32,
                 "id":1,
                 "name":"ground",
                 "rotation":0,
                 "visible":true,
                 "width":128,
                 "x":0,
                 "y":96
                }, 
                {
                 "class":"",
                 "height":32,
                 "id":2,
                 "name":"pipe",
                 "rotation":0,
                 "visible":true,
                 "width":32,
                 "x":16,
                 "y":64
                },

But I see that Tile Collision Editor exists. Maybe it can be more useful but I don’t know how to export colliders to JSON. I created a collider in this editor:

https://media.discordapp.net/attachments/524610627545595906/1079014388310229062/image.png

I added this object to a map:

https://media.discordapp.net/attachments/524610627545595906/1079015432532541490/image.png?width=403&height=406

But when I export it I don’t see these colliders. I see colliders that I added as objects:

The colliders are stored in the tileset. Since you know which tile is used at any given cell, you can get its collision data from the tileset.
