How to modify the default tile map collider 2D Unity?

Question

I'm new at unity 2D,I crated this scene so far, But I had problem with the Tile map 2D collider (that comes by default when I created a grid and used a palette to create this simple scene) :

I want to edit this collider, for example the true now is behaving as an obstacle, and I don't want that, so I need to remove it or something like that if it's possible.

Answer 1

You can "remove" the collider from specific tiles by selecting them in the assets and select Collider Type -> None (See TileMapCollider2D

The Tilemap Collider 2D component does not generate any Collider shapes for this Tile.
