The H5MMods folder is not being created for editing index.bin.

I recently encountered a problem with finding the index.bin file of a created map. The issue is that I've had an idea for a while to add new tiles and ground textures to both the editor and the game, in addition to the standard ones (grass, sand, lava, snow). But to add them, they need to be saved in the editor. I tried creating tiles in the editor both with and without maps. As a result, I only managed to create and save one tile without texture or color, and it is always hidden by the editor.
In addition, I also created an empty object before the tile, which is now also stuck in the editor.
Overall, I'm stuck in this dead-end situation and don't know what to do next. If anyone knows how to add new tiles to the editor so that they are displayed correctly, I would be very grateful for any help.
