How to rig a backpack

hi, i made a backpack in blender but i don’t know how to rig to epic skeleton. i am researching but i didn’t see any example model or any video to explain. i want to make the last of us backpack(something similar to that). but i don’t know where to rig how to rig, do you guys can explain to me or can you give me links that any video or picture or something to help

Did you tried to “Add assest” to bone?

what do you mean by add assest

this is not my question

I would just make a root connection on the backpack and attach that root to either the hips or one of the spine elements of your human skeleton
