How can I describe items in Minecraft 1.16.5?

I would like to know with which command I can describe items in 1.16.5, as well as in the picture in the appendix. LG.

There's no order.
For this you have to program a plugin or download one.

On http://mcstacker.net you can generate / give commands, where you can give yourself an item with a lore (description in English):

And this is an example Command:

/ give @p dead_bush {display: {Lore: ['{"text": "Banger bush"}']}}
