Does anyone have any idea how I can leave the "hotbar_slot_selector" below the number??

Create a new folder and name it as your resource pack. For example, "Hotbar Selector Pack". Inside the resource pack folder, create a new folder called "textures". Inside the "textures" folder, create a new folder called "gui". Inside the "gui" folder, create a new image file named "hotbar.png".

Create a new layer above the hotbar slots in the image editor. On the new layer, add the text "hotbar_slot_selector" below the selected hotbar slot number using a font and color of your choice. Save the "hotbar.png" image file and close the image editor. Create a new text file in the resource pack folder and name it "manifest.json". Paste the following code into the "manifest.json" file:

{
"format_version": 1,
"header": {
"name": "Hotbar Selector Pack",
"description": "A resource pack that adds a hotbar selector HUD to the game.",
"uuid": "your-pack-uuid",
"version": [1, 0, 0],
"min_engine_version": [1, 17, 0]
},
"modules": [
{
"type": "resources",
"uuid": "your-resources-uuid",
"version": [1, 0, 0]
}
]
}
