Minecraft Note System Using Command Blocks

I have found that in most games nowadays, when you are exploring a room or look in a drawer you fun some sort of note which has important information on it and allows you to progress in the game. I thought this would be really useful in Minecraft so I came up with my own note system.
BELOW ARE THE COMMANDS YOU WILL NEED:
BOTTOM ALWAYS ACTIVE REPEAT COMMAND BLOCK:
execute unless entity @p[nbt={SelectedItem:{id:"minecraft:paper",tag:{display:{Name:'{"text":"Note Title"}'}}}}] run setblock ~ ~2 ~ air
TOP ALWAYS ACTIVE REPEAT COMMAND BLOCK:
execute if entity @p[nbt={SelectedItem:{id:"minecraft:paper",tag:{display:{Name:'{"text":"Note Title"}'}}}}] run setblock ~ ~1 ~ redstone_block
TELL RAW GENERATOR ON MINECRAFT.TOOLS
minecraft.tools/en/tellraw.php
GIVE INVISIBLE ITEM FRAME COMMAND
/give @p item_frame{EntityTag:{Invisible:1b}}
