Tilemap node with 2 textures

PabloDev

Hello, a question about the tilemap node. I have a tilemap node and it has two textures, as you can see in the image.

Ok, now I want to use SetCell, so how do I indicate that one or the other texture should be used for setCell ?, that is, each tilemap has its tiles, so as I indicate "Put a tile that is in the second texture".

I guess it is using TileSet.TileSetTexture but i don't know how i should handle the textures any example?

edit: I might be misunderstanding but I think you want to have 2 tilesets in your node tree as the video explains towards the end.
