How to select only deformation bones?

Question

Is there a way to select all bones from the vertex group of the mesh?

I have too many overlapping bones that are very tedious to work and some are non-deformer which I wanted to hide and only work with the ones that are applied under the vertex group for weight Paint. I can always do this by hand but it'll be extremely time-consuming to go everyone.

It is script Highlights bones with deform in pose mode

import bpy

mesh_objects = []

for object in bpy.data.objects:
    if object.type == 'MESH':
        mesh_objects.append(object)   

vertex_group_names = []

for object in mesh_objects:
    if object.vertex_groups is not None:
        for group in object.vertex_groups:
            vertex_group_names.append(group.name)

rig_name = bpy.context.active_object.name

rig_bones = bpy.data.armatures[rig_name].bones

for bone in rig_bones:
    if bone.use_deform is True:
        if bone.name not in vertex_group_names:
            bone.select = True

When bones in vertex groups need little change / delete "not"
