How do you connect accessories/items to your rig

Im currently working on a character right now and I’ve came into a little issue with the rig

The object/eyepatch wont move when I move the head
this is what the rig looks like:

this is what happens when I try to move the head:

A clearer image of this:

If anybody can point out what i need to do to fix this or what im doing wrong, would be so much appreciated, also if theres any problems with my rig feel free to tell me how to fix it, since im relatively new to rigging characters

If the eyepatch is a separate object from the head, you can parent the eyepatch directly to the head bone.

If you need more control over how the eyepatch deforms you could also parent the eyepatch to the armature then weight paint it with whatever bones you want influencing it
