skript for only the player that placed the certain block can break it and pick it up, no one else. Also skript for upgrading a gen.

Ok so i have a gen script for coal block(coal),iron block (iron ingot),gold block (gold ingots),diamond block (diamond),netherite block (netherite ingot) and obsidian (netherstar). i have the script for the generators but i dont know how to make the script for when you Shift+left click it upgrades the gen and when you left click it picks up the gen anddd only the person that placed the block can pick it up. So can you please help me make those 3 things.

what is the command to get the upgrade wand
