The Courier Spirit Add-on 1.21+/1.20+

Now you no longer have to trek halfway across the map for lost drops. After death, a special entity in the form of a Courier Spirit appears in the world, which collects your items and delivers them to your respawn point. The The Courier Spirit mod saves you from long trips back to your death site and makes retrieving your inventory much more convenient in Minecraft.
The spirit displays the player's name and the number of items, can navigate around obstacles or pass through blocks, and even works across dimensions.
