Part of my mesh is not affected by bones Working on Blender 2.83.3

SWORD FIGHTER MODEL
I'm trying to rig a cartoon character just for fun. I'm comfortable with most blender features but this one : Rigging.
Most of my rig is working relatively well (still figuring things out by tries and errors). However here I tried everything to no avail.
I moved the arm. As you can see it works.

Here is my problem:

As you can see I made a bone rotation. Everything moves but the eyes (pupils and black part of the eye.)
Everything looks correctly parented, and I joined every part of my mesh together.
I tried to make some bones really close to these parts, no result.
I tried to weight paint, without any result.
Are these meshes &quot;too thin&quot; to be affected? Should I &quot;stick&quot; the eyes to the body in some way? I don't get it.
Thanks a lot for your time.

I believe from looking that they are separate meshes, in which case you must join them with Ctrl-J and then you should be able to weight paint it, if not you could separate the eyes and parent the separated object to a bone so that it rotates as if it were attached (but this would not morph the mesh like regular bones would).
