How to use /give command with custom NBT

I'm coding a mod that adds runes to items. They work like enchantments. To do that, I'm using custom NBT tag with the block "SET NBT TAG...". It works, but i can't /give myself an item with this custom tag.

Here is the command I tried : /summon item ~ ~1 ~ {Item:{id:netherite_chestplate,tag:{Rune:Resistance}},Count:1}         I wrote it correctly.

Is this even possible ?
