Modern Backpacks Add-on 1.21+/1.20+

Neither Bundles nor Bags are likely to replace the familiar Backpacks in Minecraft PE anytime soon. After all, Backpacks from the mod Modern Backpacks will be much more useful than Bags, as they have 60 slots in which you can place anything. In addition, all of this works within the Redstone system, meaning you can deposit and withdraw items just like in Chests.


Crafting

Then you can click on the item to open it.


By crouching, you can place the Backpack.


This simple mechanism allows you to collect items from the Backpack into the Chest.
